The perimeter of a square is 80 cm. What is the area?

A = 400 cm^2

Step-by-step explanation:

The perimeter of a square is given by

P = 4s where s is the side length

80 = 4s

Divide each side by 4

80/4 = 4s/4

20 =s

We want to find the area of the square

A = s^2

A = 20^2

A = 400 cm^2

good luck!
