the area of the rectangular wall of a barn is 198 square feet. Its length is 4 feet longer than twice its width.
We have to find the length and width of the wall of the barn.
Let the width of the wall of the barn \(b=x\)
So the length of the wall of the barn \(l=2x+4\)
We know that the area of the rectangular wall of a barn \(A= lb\)
