Question

Which of the following represents the area of a rectangle whose length is x + 1 and whose width is
x + 11?
Answer

x^2+ 12x + 11

x^2+ 11x + 12

x^2+ 10x + 11

x^2+ 11

Answer 1

area of rectangle = length x width
(x + 1)(x + 11) = x^2+ 12x + 11

Answer 2

Area of a rectangle = lw
a = (x+1)(x+11)
= x^2+11x+x+11
= x^2+12x+11
area = a: x^2+12x+11
