area= length x width
since its a square and squares have their lengths and widths the same, we will say that x represents length and width.
so...
area=x*x
area=x^2
we know that the area of the pool is 183.84 square meters so plug that into area
183.84=x^2
solve for x by square rooting both sides
you will get x=... (square root of 183.84)
so that is x value is your width and length.
therr are 4 sides on a square so multiple x by 4 to get perimeter.
