Question 1.
Collect the area measurements of your classmates’ robot bodies. Make a line plot using everyone’s area measurements.
Areas of Robot Bodies

a. How many different measurements are on the line plot? Why are the measurements different?
b. What does this tell you about the relationship between area and perimeter?
Answer:
a.
There are four different kinds of measurements represented on the number line. They are different in values because the values of every rectangle is different from each other.

b. Perimeter is the measurement of the distance around a shape. Area is the measurement of space inside a shape. Area and Perimeter are not having any relationship because they are totally two different things. Perimeter is going to be more than the area of the rectangle.

Explanation:
a.

Area of the A rectangle = Length × Width = 4cm × 4cm = 16 square cm.
Area of the B rectangle = Length × Width = 2cm × 2cm = 16 square cm.
Area of the C rectangle = Length × Width = 8cm × 6cm = 48 square cm.
Area of the D rectangle = Length × Width = 5cm × 2cm = 10 square cm.
Area of the E rectangle = Length × Width = 5cm × 2cm = 10 square cm.
Area of the F rectangle = Length × Width = 7cm × 2cm = 14 square cm.
Area of the G rectangle = Length × Width = 7cm × 2cm = 14 square cm.
There are four different kinds of measurements represented on the number line. They are different in values because the values of every rectangle is different from each other.

b. Perimeter is the measurement of the distance around a shape. Area is the measurement of space inside a shape.
For Example : If a rectangle having length as 2cm and width as 1cm.
Perimeter = 2 (Length + Width) = 2 ( 2cm + 1cm) = 2 × 3cm = 6cm.
Area = length × Width = 2cm × 1cm = 2 square cm.
Area and Perimeter are not having any relationship because they are totally two different things.
