Question

The area of a square is 4 square meters. How long is each side? Please show every step.
Thank you! :)

Answer 1

since you're trying to find the side lenghts of a square, all we need to do is square root the area. So, the square root of 4 (the area) is 2.

So, all of the sides of the square are 2 meters long.

Answer 2

since the area of the square is given by side length squared....

let s=side length
s²=4
s=±√4 or±2

but since length can never be negative, we ignore there extraneous answer-2 and conclude the side length s=2
