We know the perimeter of a square is 4 times the length of one of it's sides.  So 

36 = 4 * (9x)

36 = 36x

x=1

First write down what you know
1) a perimeter is the sum of the length of all sides
2) a square has 4 sides
3) All sides in a square are equal so.....
we can write that 36= 4 * (9x)
4*9x= 36x
36x=36
x=1
