A rectangle has a length that is three times the width . The perimeter of the rectangle is 40 feet. what is the area of the rectangle

The area is 15 feet

Step-by-step explanation:

So you are going to need two different equations-

l = w(3)

2l + 2w = 40

Insert the first equation into the second-

2(3w) + 2w = 40

Simplify this equation-

6w + 2w = 40

8w = 40

Divide both sides by 5

w = 5

Solve first equation

l = 5(3)

l = 15

Then find the area-

5 x 15 = 75

step-by-step explanation:

because it just is

wait this depends wether emily and zach how they are thinking.

yes they are the same.
