Question

Nick has a new pool in his backyard in the shape of a rectangle. He needs to buy a cover for the winter months. Nick knows that the pool is 384 square feet and the width is 16 feet. 1. Show the formula to determine the area of a rectangle. 2. Rearrange the formula to find the unknown length of Nick's pool 3. Calculate the length of Nick's pool. 4. If Nick had to buy a cover that was too long (30 foot), how much extra area would be left over after the pool is covered?

Answer 1

1. Show the formula to determine the area of a rectangle.

area = length x width

2. Rearrange the formula to find the unknown length of Nick's pool

length = area / width

3. Calculate the length of Nick's pool.

length = 384 / 16 = 24 feet

4. If Nick had to buy a cover that was too long (30 foot), how much extra area would be left over after the pool is covered?

(30 - 24) * 16 = 6 * 16 = 96 square feet
