Problema Solution
The perimeter of a rectangle is 110 ft. Find the width if the length is 5 less than twice the width.
Answer provided by our tutors
let
w = the width
l = the length
The perimeter of a rectangle is 110 ft:
2(l + w) = 110
the length is 5 less than twice the width
l = 2w - 5
by solving the system of equations:
2(l + w) = 110
l = 2w - 5
we find:
l = 35 ft
w = 20 ft
