Question

If the width of a rectangle is x + 2 and the length is twice as long, what is the area?
A. 6x + 12
B. 2x² + 6x + 4
C. 2x² + 8x + 6
D. 2x² + 8x + 8

Answer 1

width , x+2
length , 2(x+2)
area = length x width
=2(x+2)(x+2)
= 2(x+2)^2
=2x^2+8x +8

Answer 2

(x+2)(2x+4)
2x^2+4x+4x+8
2x^2+8x++8
