Question

Find the area of a square with a side measure of 3x − 6 feet.

Question 5 options:

9x2−36x+36 sq. ft.

9x2−6 sq. ft.

9x2+36x+36 sq. ft.

9x2+36 sq. ft.

Answer 1

Area of a square: s^2

Because we know the length of one side, we can multiply it by itself to find the area.

(3x - 6)(3x - 6)

9x^2 - 18x - 18x + 36

Combine like terms.

9x^2 - 36x + 36

The correct answer is A, or the first answer.
