Answer:
<h3>The length is 44 feet</h3><h3>The width is 20 feet</h3>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
Perimeter = 128 feet
The width is 24 feet less than the length is written as
w = l - 24
128 = 2l + 2( l - 24)
128 = 2l + 2l - 48
Group like terms
4l = 176
Divide both sides by 4
l = 44
The length is 44 feet
Substitute l = 44 into w = l - 24
w = 44 - 24
w = 20
The width is 20 feet
Hope this helps you
