Question

The measure of one side of a square is (x +4). What is the difference of the area of the square and the

perimeter of the square?
a. 2(x + 4)
b. x(x +4)
C. 2x + 4

Answer 1

b. x(x+4)

Explanation:

The measure of one side of a square is (x +4). What is the difference of the area of the square and the perimeter of the square?

A = s² and P = 4s

s² - 4s =

(x+4)(x+4) - 4(x+4) =

x² + 4x + 4x +16 - 4x - 16 =

x² + 4x now factor out x

x(x+4) so the answer is b
