| A lot has the dimensions of 90’ by 150’. The homeowner wants to build a fence around the entire lot, fencing costs $6.95 per linear foot. Find the cost of materials. |

Definition
The fence would go around the perimeter.
P = 2(length) + 2(width)
P = 2(90) + 2(150)
P = 180 + 300
P = 480'
To find the cost we need to multiply our footage by cost.
(480)(6.95)

Total Cost = (20)(40)
Total Cost = $800
