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.
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.
