		(9x - 1) feet
		(9x + 1) feet
		(3x + 1) feet
		(3x - 1) feet

lgbasallote · Answer

area = s^2
9x^2 - 6x + 1 = s^2

s = $\sqrt{9x^2 - 6x +1}$
s = $\sqrt{(3x-1)^2}$

It is square.  so all sides are equal l=w=x.  Area will be the product of two sides.
A=9x^2-6x + 1
(3x-1)(3x-1)
3x-1 = length of side.
