You just purchased a rectangular waterfront lot along a river's edge. The perimeter of the lot is 360 feet. To create a sense of privacy, you decide to fence along three sides, excluding the side that fronts the

the two sides widths cost only $8 per foot. The total cost of the fencing along the three sides comes to
$3280. 5a.1> What are the lot's dimensions? 5a.2> You are considering using the expensive fencing on
