The area of a square is A=L² where, L is the length of the square and A is the area of the square.

So,
$L= \sqrt{A}$ ..........we get this by square rooting on both sides in the formula

$L= \sqrt{ x^{2} -12x+36}$

$L= \sqrt{ (x)^{2} -2*x*6+ (6)^{2} }$ ..............(a-b)²=a²-2ab+b²

$L= \sqrt{ (x-6)^{2} }$ ..................................(a-b)²=a²-2ab+b²

L=x-6

...............................square cancels square root

So, the expression that represents the length of one side of square is x - 6 inches.
