Question

a rectangular swimming pool with sides 81 feet by 106 feet needs a cover. determine how to find the size of the cover needed. to determine the size of the cover needed, calculate the of the pool, which will have units of (dropdown options include area, perimeter)

Explanation:

Step1: Understand the problem

We need to find the size of the cover for a rectangular pool. The cover should fit the surface of the pool, so we need the measure of the surface, which is the area. The perimeter is the distance around the pool, which isn't what we need for the cover size.

Step2: Determine the units

Since the sides are in feet, the area of a rectangle is calculated as length times width, so the units for area will be square feet (because we multiply two lengths in feet: \( \text{feet} \times \text{feet} = \text{square feet} \)).

Answer:

First dropdown: area; Second dropdown: square feet
