Question 143591: the lenght of a rectangle is 4 feet less than twice the width. the perimeter is 28 feet. find the length and width fo the rectangle. Answer by vleith(2983) (Show Source):
You can put this solution on YOUR website! Perimeter is the sum of all the sides.
Let w be the width.
L = 2w-4
P = w + l + w + l
28 = w + 2w -4 + w + 2w -4
28 = 6w - 8
36 = 6w
6 = w
l = 12 - 4
l = 8
Does that work?
28 = 12 + 16 check!
