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?

Step-by-step 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

any options?

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
