Question

The formula for finding the area of a square that has a side length, s, is A = s^2. If a square has an area of 40 square units, what is the length of a side?

Answer 1

A = s^2
A = 40

40 = s^2...by taking the square root of both sides, u eliminate the ^2
sqrt 40 = s
6.32 = s <===

Answer 2

The length of a side would be the square root of s (40). The square root of 40 is 6.325 units, which is the length of one side.
