Problema Solution
the area of a rectangular wall of a barn is 60 square feet. its length is 4 feet longer than its width. find the length and width of the wall of the barn
Answer provided by our tutors
let
l = the length of the rectangular wall, l>0
w = the width of the rectangular wall, w>0
A = 60 ft^2 the area of the rectangular wall
A = l*w
l*w = 60
its length is 4 feet longer than its width:
l = 4 + w
plug l = 4 + w into l*w = 60
(4 + w)*w = 60
by solving we find:
w = 6 ft
click here to see the step by step solution of the equation:
l = 4 + 6 = 10 ft
the length of the wall is 10 ft.
the width of the wall is 6 ft.
