Explanation:

edge says trust me

Based on the calculations, the area of this pentagonal pool that needs to be covered is equal to: B. 960 ft².

Given the following data:

Radius of pool = 20.10 ft.

Side length of pool = 23.62 ft.

How to calculate the area of the pool?

Mathematically, the area of a regular pentagon can be calculated by using this formula:

A = ¹/₄√(5(5 + 2√5)a²)

Where:

a is side length.

Substituting the parameters into the formula, we have:

A = ¹/₄√(5(5 + 2√5)23.62²)

A = ¹/₄√(5(5 + 2√5)557.9044)

A = 959.86 960 ft².
