The rectangle has two lengths and two breadths. To find the perimeter of the rectangle we have to add the length and breadth. It is measured in units. It is denoted by P.<\/p>\n<p><strong>Area:<\/strong> The area of the rectangle formula helps to calculate the length and breadth of the two-dimensional closed figure. To find the area of the rectangle we have to multiply the length and breadth of the rectangle. It is measured in square units.

Go through the below questions and solve the problems using the Area and Perimeter of the Rectangle formula.<\/p>\n<p><strong>1. Find the length of the rectangular plot whose breadth is 11 cm and the area is 165 cm\u00b2. Also, find the perimeter of the rectangle?<\/strong><\/p>\n<p>Solution:<\/p>\n<p>Given,<br \/>\nBreadth = 11 cm<br \/>\nArea = 165 cm\u00b2<br \/>\nArea of the rectangle = l \u00d7 b<br \/>\n165 sq. cm = l \u00d7 11 cm<br \/>\nl = 165\/11<br \/>\nl = 15 cm<br \/>\nThus the length of the rectangle is 15 cm.<br \/>\nWe know that,<br \/>\nPerimeter of the rectangle = 2(l + b)<br \/>\nP = 2(15 + 11)<br \/>\nP = 2(26)<br \/>\nP = 52 cm<br \/>\nThus the perimeter of the rectangle is 52 cm.<\/p>\n<p><strong>2. Find the Perimeter of the Rectangle whose length is 10 cm and breadth is 8 cm?<\/strong><\/p>\n<p>Solution:<\/p>\n<p>Given, Length = 10 cm<br \/>\nBreadth = 8 cm<br \/>\nWe know that,<br \/>\nPerimeter of the rectangle = 2(l + b)<br \/>\nP = 2(10 cm + 8 cm)<br \/>\nP = 2(18 cm)<br \/>\nP = 36 cm<br \/>\nTherefore the perimeter of the rectangle is 36 cm.<\/p>\n<p><strong>3. Find the area of the rectangle whose length is 14 meter and width is 10 meters?<\/strong><\/p>\n<p>Solution:<\/p>\n<p>Given,<br \/>\nLength = 14 meter<br \/>\nWidth = 10 meter<br \/>\nWe know that,<br \/>\nArea of the rectangle = l \u00d7 w<br \/>\nA = 14 m \u00d7 10 m<br \/>\nA = 140 sq. meters<br \/>\nTherefore the area of the rectangle is 140 square meters.<\/p>\n<p><strong>4. A rectangular plot has its length of 16 cm and a perimeter of 60 cm. Find the width of the rectangular plot?<\/strong><\/p>\n<p>Solution:<\/p>\n<p>Given,<br \/>\nLength = 16 cm<br \/>\nPerimeter = 60 cm<br \/>\nWidth = ?<br \/>\nWe know that<br \/>\nThe perimeter of the rectangle = 2(l + w)<br \/>\n60 cm = 2(16 cm + w)<br \/>\n16 + w = 60\/2<br \/>\n16 + w = 30<br \/>\nw = 30 &#8211; 16<br \/>\nw = 14 cm<br \/>\nThus the width of the rectangular plot is 14 cm.<\/p>\n<p><strong>5. Find the area and perimeter of the rectangle whose length and breadth are 12 m and 6 m?<\/strong><\/p>\n<p>Solution:<br \/>\nGiven,<br \/>\nlength = 12 m<br \/>\nbreadth = 6 m<br \/>\nWe know that,<br \/>\nArea of the rectangle = l \u00d7 b<br \/>\nA = 12 m \u00d7 6 m<br \/>\nA = 72 sq. meters<br \/>\nNow find the perimeter of the rectangle<br \/>\nP = l + l + b + b<br \/>\nP = 12 m + 12 m + 6 m + 6 m<br \/>\nP = 24 m + 12 m<br \/>\nP = 36 m<br \/>\nTherefore the area and perimeter of the rectangle is 72 square meters and 36 meters.<\/p>\n<h3>FAQs on Area and Perimeter of Rectangle<\/h3>\n<p><strong>1.
