A farmer wishes to fence a rectangular area behind his barn. The barn forms one end of the rectangle and the length of the rectangle is three times the width. How many linear feet of the fence must he buy if the perimeter of the rectangle is 320 feet?

Therefore, he must buy feet of fence to form barn if the perimeter of the rectangle is feet.

Length of the rectangle

as

Hence, the width of the rectangular area is .

and

Length of the rectangle

                                       = 3 × 40
