Question

A square window has an area of x2 + 22x + 121 square feet. Find the length of one side of the square.

A) (x + 11) feet

B) (x – 11) feet

C) (x – 6) feet

D) (x + 6) feet

Answer 1

x + 11 ft

Explanation:

x² + 22x + 121 ft² = area of square

x² + 11x + 11x + 121 ft² = side²

x(x + 11) + 11(x + 11) ft² = side²

(x + 11)(x + 11) ft² = side²

(x + 11)² ft² = side²

x + 11 ft = side²

Answer 2

The answer is A(x+11)
