Answer:

W=10

L=18

Step-by-step explanation:

So the equation for finding the perimeter of a rectangle is


2w + 2l = p


w=width

l=length

p=perimeter


Since the perimeter is 56 feet, and the length is 2 feet less than twice the width, then:

w=?

l=(2w-2)

p=56

So plug this info in-

2w + 2(2w-2) = 56

Then distribute-

2w + 4w - 4 = 56

Combine like terms

6w=60

Divide both sides by six

w=10

And to find length, plug width into the equation for length-

l=(2(10)-2)

l=18
