Answer: The required length of a side of the square is (x - 6) units.

Step-by-step explanation:  Given that the area of a square is as follows :

A(x)=x^2-12x+36~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We are to find the length of a side of the square.

We know that

all the sides of a square have equal length l, and its area is given by

A=l^2.

From expression (i), we have

A(x)\\\\=x^2-12x+36\\\\=x^2-2\times x\times 6+6^2\\\\=(x-6)^2.

Therefore, the required length of a side of the square is (x - 6) units.
