Problema Solution
The area of a rectangular wall of a barn is 70 square feet. Its length is 4 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, then '2w+4' represents the length:
70=w(2w+4)
w=5
2*5+4=14
The barn is 5 feet wide and 14 feet long.
