Math CentralQuandaries & Queries


Question from nayle, a student:

The owner of a parking lot at the beach wants to increase the parking area of the lot. If the owner increases each of the dimensions of the rectangular lot by half its original value, by what factor will the parking lot increase?


Suppose the current parking lot is L feet long and W feet wide. The area is then L × W square feet. What will be the length of the expanded lot? What will be its width? What will be its area? How does this compare to L × W square feet?
