Problema Solution
the area of a rectangular wall of a barn is 176 square feet. its length is 6 feet longer than twice its width. find the length and width of the wall of the barn
Answer provided by our tutors
let
w = the width of the wall, w>0
l = the length of the wall, l>0
Area = 176 ft^2 and Area =w*l
w*l = 176
length is 6 feet longer than twice its width
l = 2w + 6
by solving the system of equations
w*l = 176
l = 2w + 6
we find
w = 8 ft
l = 22 ft
the length and the width of the wall of the barn are 22 ft an 8 ft.
