Question

If the perimeter of the square below is 40 in. The area of this square is ?

Answer 1

Since you know the perimeter is 40in (the distance around the square or all the sides added together) and you know that each side must add up to a total of 40in, you can use that to answer the following:

a) What is the length of each side?

b) How does the area relate to the side lengths?

a) Knowing that you’re dealing wit a square, every side must be equal in length. Since there are 4 sides, and the perimeter is 40, each side must be 10in. 40 divided by 4 (sides).

b) The area of a square can be interpreted by the equation “length times width”.

The length is the same as the width (10”), therefore 10 times 10 = 100 m².

Answer 2

Use the formula for the perimeter of a square to determine the length of each side.

Then use the formula for the area of a square.
