Problema Solution
The length of a rectangular piece of steel is 5 meters less than triple the width. the perimiter of the piece is 54 meters. fint the length of the peice. find the width of the peice.
Answer provided by our tutors
let
l = the length of the rectangular piece of steel
w = the width of the rectangular piece of steel
the length of a rectangular piece of steel is 5 meters less than triple the width
l = 3w - 5
the perimeter of the piece is 54 meters
2(l + w) = 54
by solving the system of equations
l = 3w - 5
2(l + w) = 54
we find
l = 19 m
w = 8 m

the length if 19 meters.
the width is 8 meters.
