Question

The area of a rectangle is expressed as (12m + 18) square feet. If the width of the rectangle is 6 feet, choose an expression to represent the length of the rectangle.

A.

1. 6(12m + 18) feet

B.

1. (m + 1) feet

C.

1. (2m + 3) feet

D.

1. (6m + 12) feet

Answer 1

The equation for the area of a rectangle is w times l or A = wl

In order to find the length on its own from this equation, we need to rearrange the equation to have just l on one side. To make l by itself, we need to divide by w on both sides which gives : A/w = l

A/w = l

If the width is 6 : w = 6

The area is (12m + 18) : A = 12m+18

Then we need to plug in the equation to get : (12m +18)/6

dividing 12m/6 = 2m

dividing 18/6 = 3

then the length is (2m+3) feet
