You can put this solution on YOUR website!
If you have an area of a square, then you can find the length of the sides. This is because the area is given as
A=x%5E2 where x is the length of the side
So if you take the square root of both sides
sqrt%28A%29=sqrt%28x%5E2%29
x=0%2B-sqrt%28A%29it's equal to plus-minus square root of A, but we'll ignore the negative answer (a negative length doesn't make sense)
When you take the square root of the area, then you'll find the length of the sides.
