--------
Formula:: Area = (side)^2
------
side = sqrt(Area)
------
Your Problem::
x = sqrt(400)
--
x = 20 inches

How do you find area of square if you are given area of the square is 400? You do not find it! You are GIVEN the area.

If x is the length of one side, then for a square, ALL of the sides is x each. The area is x%2Ax.

Let x be side length of a SQUARE, and A be the area of the square.
x%5E2=A
x=sqrt%28A%29
