Problema Solution
The length of the bar was 3.4 feet more than twice the width and the perimeter was 45.8 feet. Find the length and width
Answer provided by our tutors
let
l = the length of the bar
w = the width of the bar
the length of the bar was 3.4 feet more than twice the width
l = 3.4 + 2w
the perimeter was 45.8 feet
2(l + w) = 45.8
by solving the system of equations
l = 3.4 + 2w
2(l + w) = 45.8
we find
l = 16.4 ft
w = 6.5 ft
