Problema Solution
The Perimeter of a rectangle is 28ft. Find the length of the rectangle if the length is 4ft less than 2 times the width
Answer provided by our tutors
let
l = the length of the rectangle
w = the weight of the rectangle
the perimeter of a rectangle is 28 ft:
2(l + w) = 28 divide both sides by 2
l + w = 14
the length is 4 ft less than 2 times the width:
l = 2w - 4
by solving the system of equations:
l + w = 14
l = 2w - 4
we find:
l = 8 ft
w = 6 ft
