Problema Solution
The length of a rectangle is 7 meters longer than its width. what is the width of this rectangle if its perimeter is equal to 130 meters
Answer provided by our tutors
let
l = the length of the rectangle
w = the width of the rectangle
P = 130 m the perimeter of the rectangle
the length of a rectangle is 7 meters longer than its width:
l = 7 + w
the perimeter of a rectangle is P = 2(l + w) thus
2(l + w) = 130 divide both sides by 2
l + w = 65
by solving the system of equations:
l = 7 + w
l + w = 65
we find:
l = 36 m
w = 29 m

the width of the rectangle is 29 meters.
