Answer:
The length of one side of the square is (x-6) m
Explanation:
The correct question is
A square has an area of x^2-12x+36 square meters. What expression represents the length of one side of the square?
we have

we know that

so
Rewrite the given expression as perfect squares

----> equation A
Remember that the area of a square is equal to
----> equation B
where
b is the length side of square
so
equate equation A and equation B


therefore
The length of one side of the square is (x-6) meters
