Problema Solution
the perimeter of a rectangle is 72m. the length is 6 meters less than three times the width. find the length and width
Answer provided by our tutors
let
l = the length of the rectangle
w = the width of the rectangle
P = 72 m in the perimeter of the rectangle
the length is 6 meters less than three times the width
l = 3w - 6
the perimeter P = 2(l + w)
2(l + w) = 72 divide both sides by 2
l + w = 36
by solving the system of equations
l = 3w - 6
l + w = 36
we find
l = 25.5 m
w = 10.5 m
