Question

The area of a square is 100 cm². what is the perimeter?

Answer 1

40cm

Explanation:

We know that the formula for area of a square is side length squared or
`s^2`

In this case,
`s^2=100`. So we can go through the following steps in order to solve for s

`s^2=100\\√(s^2) =√(100) \\\\s=10`

If one side equals 10, and we know all squares have 4 equal sides, then we can multiple 10 * 4 or add 10+ 10 + 10 + 10.

Our outcome is 40!

Answer 2

40 cm

Explanation:

a square has 4 equal length sides, to get area you multiply two of those sides, 10 x 10 = 100, so each side is 10cm long, adding all of the sides together gets you 40cm.
