Problema Solution
The area of a rectangular barn wall is 48 square feet. Its length is 4 feet longer than twice the width. Find the length and width of the barn wall.
Answer provided by our tutors
let 'x' represent the width, then '2x+4' represents the width
area = length * width
48 = x(2x+4)
solving for 'x' we have a positive value of x=4
2*4 + 4 = 20
the wall is 4 feet wide and 20 feet long
