Problema Solution
the area of a rectangular wall of a barn is 120 square feet. Its length is 8 feet longer than twice its width. Find the length and width of the wall of the barn
Answer provided by our tutors
let 'w' represent the width in feet, then '2w+8' represents the length in feet
area = length * width, therefore:
120 = w(2w+8)
solving for 'w' we have a positive value of:
w = 6
2*6+8 = 20
the width is 6 feet, the length is 20 feet
