Find the perimeter of the square: A = 400 in second power

How do you do the work to get 80in.

By definition a square has all 4 sides equal, the area of a square is sxs or s^2, so s^2 = 400, s = square root of 400 = 20. All sides will be equal to 20 m. The perimeter is the sum of the sides or 4 x s or 80.

Steps:

A= L^2

Where L is length of the side

400=L^2 》》》》》 square root

L= 20 all sides of square are 20 m

P = 4L

=4(20)

=80m
