Problema Solution
The length of a rectangle is 3 feet less than twice the width of the rectangle. If the perimeter of the rectangle is 114 feet, find the width and the length.
Answer provided by our tutors
let
l = the length of the rectangle
w = the width of the rectangle
the length of a rectangle is 3 feet less than twice the width of the rectangle
l = 2w - 3
the perimeter of the rectangle is 114 feet
2(l + w) = 114 divide both sides by 2
l + w = 57
by solving the system of equations
l = 2w - 3
l + w = 57
we find
l = 37 ft
w = 20 ft
