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
