\nAnswer:
\n\"Eureka
\na. A = 63 cm2 <\/sup>, A = 54 cm2<\/sup>,<\/p>\n

Explanation:
\nAs shown in figure A length = 9 cm , breadth = 7 cm,
\nArea of rectangle is = l X b = 9 cm X 7 cm = 63 square cm,
\nand in figure B length = 6 cm , breadth = 9 cm,
\nArea of rectangle is = l X b = 6 cm X 9 cm = 54 square cm.<\/p>\n

b. P = 32 cm,\u00a0 P = 30 cm,<\/p>\n

Explanation:
\nAs shown in figure A length = 9 cm , breadth = 7 cm,
\nPerimeter of rectangle is =2 X (l + b) = 2(9 cm + 7 cm) =
\n2 X (16 cm) = 32 cm,
\nand in figure B length = 6 cm , breadth = 9 cm,
\nPerimeter of rectangle is =2 X (l + b) = 2 X (6 cm + 9 cm) =
\n2 X (15 cm) = 30 cm.<\/p>\n

\nA = _____30 cm2<\/sup>_______
\nAnswer:
\nPerimeter = 22 cm,
\nArea =\u00a030 cm2<\/sup>,<\/p>\n

Explanation:
\nGiven length = 5 cm and breadth = 6 cm,
\nPerimeter of rectangle is =2 X (l + b) = 2 X (5 cm + 6 cm) =
\n2 X (11 cm) = 22 cm,
\nArea of rectangle is = l X b = 5 cm X 6 cm = 30 square cm.<\/p>\n

b.
\n\"Eureka
\nP = ____22 cm_______
\nA = ____ 24 cm2<\/sup>________
\nAnswer:
\nPerimeter = 22 cm,
\nArea = 24 cm2<\/sup>,<\/p>\n

Explanation:
\nGiven length = 8 cm and breadth = 3 cm,
\nPerimeter of rectangle is =2 X (l + b) = 2 X (8 cm + 3 cm) =
\n2 X (11 cm) = 22 cm,
\nArea of rectangle is = l X b = 8 cm X 3 cm = 24 square cm.<\/p>\n

Question 3.
\nDetermine the perimeter of each rectangle.
\na.
\n\"Eureka
\nP = ____530 m________
\nAnswer:
\nPerimeter = 530 m,<\/p>\n

Explanation:
\nGiven length = 99 m and breadth = 166 m,
\nPerimeter of rectangle is =2 X (l + b) = 2 X (99 m + 166 m) =
\n2 X ( 265 m) = 530 m.<\/p>\n

b.
\n\"Eureka
\nP = ____450 cm________
\nAnswer:
\nPerimeter =\u00a0 450 cm,<\/p>\n

Explanation:
\nGiven length = 75 cm and breadth = 1 m 50 cm,
\nwe know 1 m = 100 cm ,
\nso breadth =\u00a0 1 X 100 cm + 50 cm =150 cm,
\nPerimeter of rectangle is =2 X (l + b) = 2 X (75 cm + 150 cm) =
\n2 X (225 cm) = 450 cm.<\/p>\n

Question 4.
\nGiven the rectangle\u2019s area, find the unknown side length.
\na.
\n\"Eureka
\nx = ____10 cm________
\nAnswer:
\nUnknown side length = 10 cm,<\/p>\n

Explanation:
\nGiven width of rectangle as 8 cm and area as 80 square cm,
\nand unknow side length is x cm, we know area of rectangle is
\nlength X breadth, So 80 sq cm = 8 cm X x cm,
\nSo x cm = 80 sq cm \u00f7 8 cm = 10 cm,
\ntherefore unknown side length = 10 cm.<\/p>\n

b.
\n\"Eureka
\nx = ____7 cm________
\nAnswer:
\nUnknown side length = 7 cm,<\/p>\n

Explanation:
\nGiven width of rectangle as 7 cm and area as 49 square cm,
\nand unknow side length is x cm, we know area of rectangle is
\nlength X breadth, So 49 sq cm = 7 cm X x cm,
\nSo x cm = 49 sq cm \u00f7 7 cm = 7 cm,
\ntherefore unknown side length = 7 cm.<\/p>\n

Question 5.
\nGiven the rectangle\u2019s perimeter, find the unknown side length.
\na. P = 120 cm
\n\"Eureka
\nAnswer:
\nUnknown side length = 40 cm,<\/p>\n

Explanation:
\nGiven width of rectangle as 20 cm and perimeter as 120 cm,
\nand unknow side length is x cm, we know perimeter of
\nrectangle is 2 X (length + breadth),
\nSo 120 cm = 2 X (x cm + 20 cm),
\n120 cm \u00f7 2 = (x cm + 20 cm),
\n60 cm = (x cm + 20 cm),
\nSo x cm = 60 cm – 20 cm = 40 cm,
\ntherefore unknown side length = 40 cm.<\/p>\n

b. p = 1000 m
\n\"Eureka
\nAnswer:
\nUnknown side width = 250 m,<\/p>\n

Explanation:
\nGiven length of rectangle as 250 m and perimeter as 1000 m,
\nand unknow side width is x m, we know perimeter of
\nrectangle is 2 X (length + breadth),
\nSo 1000 m = 2 X (250 m + x m),
\n1000 m \u00f7 2 = (250 m + x m ),
\n500 m = 250 m + x m ,
\nSo x m = 500 m – 250 m = 250 m,
\ntherefore unknown side length = 250 m.<\/p>\n

Question 6.
\nEach of the following rectangles has whole number side lengths.
\nGiven the area and perimeter, find the length and width.
\na. P = 20 cm
\n\"Eureka
\nAnswer:
\nThe whole number side lengths are
\nIf length of rectangle is 4 cm then width is 6 cm or
\nlength of rectangle is 6 cm then width is 4 cm,<\/p>\n

Explanation:
\nGiven area = 24 square cm and perimeter = 20 cm of rectangles,
\nlets take length as l and width as w and we know
\narea of rectangle = length X width , 24 sq cm = l X w and
\nperimeter = 2 X (length + width) ,
\n20 cm = 2 X ( l + w), l + w = 20 cm \u00f7 2 =10 cm,
\nso l = 10 cm – w, now 24 = (10 – w) X w,
\nwe get w2<\/sup>– 10 w + 24 = 0,
\nSo w2<\/sup>– 6 w – 4 w + 24 = 0,
\nw(w – 6) – 4(w – 6) = 0, therefore w = 6 cm or w = 4 cm,
\nSo l = 10 cm – 6 cm = 4 cm or l = 10 cm\u00a0 – 4 cm = 6 cm,
\nTherfore, If length of rectangle is 4 cm then width is 6 cm or
\nlength of rectangle is 6 cm then width is 4 cm.<\/p>\n

b. P = 28 m
\n\"Eureka
\nAnswer:
\nThe whole number side lengths are
\nIf length of rectangle is 2 m then width is 12 m or
\nlength of rectangle is 12 m then width is 2 m.<\/p>\n

Explanation:
\nGiven area = 24 square m and perimeter = 28 m of rectangles,
\nlets take length as l and width as w and we know
\narea of rectangle = length X width , 24 sq m = l X w and
\nperimeter = 2 X (length + width) ,
\n28 m = 2 X ( l + w), l + w = 28 m \u00f7 2 =14 m,
\nso l = 14 m – w, now 24 = (14 – w) X w,
\nwe get w2<\/sup>– 14 w + 24 = 0,
\nSo w2<\/sup>– 12 w – 2 w + 24 = 0,
\nw(w – 12) – 2(w – 12) = 0, therefore w = 12 m or w = 2 m,
\nSo l = 14 m – 12 m = 2 m or l = 14 m – 2 m = 12 m,
\nTherfore, If length of rectangle is 2 m then width is 12 m or
\nlength of rectangle is 12 m then width is 2 m.<\/p>\n

\nAnswer:
\nUnknown side length = 10 cm,<\/p>\n

Explanation:
\nGiven width of rectangle as 6 cm and area as 60 square cm,
\nand unknow side length is x cm, we know area of rectangle is
\nlength X breadth, So 60 sq cm = 6 cm X x cm,
\nSo x cm = 60 sq cm \u00f7 6 cm = 10 cm,
\ntherefore unknown side length = 10 cm.<\/p>\n

b.

Explanation:
\nGiven width of rectangle as 5 m and area as 25 square m,
\nand unknow side length is x m, we know area of rectangle is
\nlength X breadth, So 25 sq m = 5 m X x m,

Explanation:
\nGiven width of rectangle as 40 cm and perimeter as 180 cm,
\nand unknow side length is x cm, we know perimeter of
\nrectangle is 2 X (length + breadth),
\nSo 180 cm = 2 X (x cm + 40 cm),
\n180 cm \u00f7 2 = (x cm + 40 cm),
\n90 cm = (x cm + 40 cm),
\nSo x cm = 90 cm – 40 cm = 50 cm,
\ntherefore unknown side length = 50 cm.<\/p>\n

b. P = 1,000 m

Explanation:
\nGiven length of rectangle as 150 m and perimeter as 1000 m,
\nand unknow side width is x m, we know perimeter of
\nrectangle is 2 X (length + breadth),
\nSo 1000 m = 2 X (150 m + x m),
\n1000 m \u00f7 2 = (150 m + x m ),
\n500 m = 150 m + x m ,
\nSo x m = 500 m – 150 m = 350 m,

Question 6.
\nEach of the following rectangles has whole number side lengths. Given the area and perimeter, find the length and width.
\na. A = 32 square cm
\nP = 24 cm
\n\"Eureka
\nAnswer:
\nThe whole number side lengths are
\nIf length of recatangle is 4 cm then width is 8 cm or
\nlength of rectangle is 8 cm then width is 4 cm,<\/p>\n

Explanation:
\nGiven area = 32 square cm and perimeter = 24 cm of rectangles,
\nlets take length as l and width as w and we know
\narea of rectangle = length X width , 32 sq cm = l X w and
\nperimeter = 2 X (length + width) ,
\n24 cm = 2 X ( l + w), l + w = 24 cm \u00f7 2 =12 cm,
\nso l = 12 cm – w, now 32 = (12 – w) X w,
\nwe get w2<\/sup>– 12 w + 32 = 0,
\nSo w2<\/sup>– 8 w – 4 w + 32 = 0,
\nw(w – 8) – 4(w – 8) = 0, therefore w = 8 cm or w = 4 cm,
\nSo l = 12 cm – 8 cm = 4 cm or l = 12 cm\u00a0 – 4 cm = 8 cm,
\nTherfore, If length of recatangle is 4 cm then width is 8 cm or
\nlength of rectangle is 8 cm then width is 4 cm.<\/p>\n

b. A = 36 square m
\nP = 30 m
\n\"Eureka
\nAnswer:
\nThe whole number side lengths are
\nIf length of rectangle is 3 m then width is 12 m or
\nlength of rectangle is 12 m then width is 3 m.<\/p>\n

Explanation:
\nGiven area = 36 square m and perimeter = 30 m of rectangles,
\nlets take length as l and width as w and we know
\narea of rectangle = length X width , 36 sq m = l X w and
\nperimeter = 2 X (length + width) ,
\n30 m = 2 X ( l + w), l + w = 30 m \u00f7 2 =15 m,
\nso l = 15 m – w, now 36 = (15 – w) X w,
\nwe get w2<\/sup>– 15 w + 36 = 0,
\nSo w2<\/sup>– 12 w – 3 w + 24 = 0,
\nw(w – 12) – 3(w – 12) = 0, therefore w = 12 m or w = 3 m,
\nSo l = 15 m – 12 m = 3 m or l = 15 m – 3 m = 12 m,
\nTherfore, If length of rectangle is 3 m then width is 12 m or
\nlength of rectangle is 12 m then width is 3 m.<\/p>\n","protected":false},"excerpt":{"rendered":"
