Question

A rectangle has a length that is 12 centimeters longer than its width. Let x represent the width of the rectangle. Which of the following would represent the area of the rectangle?

Answer 1

Explanation:

if x is the size of the width, then that means that the length would be x + 12.

now area is = to L * W

that means that (x) * (x+12) = Area

so multiply it out,

you get that x^2 + 12x = Area
