Question

What is the area of a regular pentagon with a side of five? Round the answer to the nearest 10th. Type the number only or your answer will be marked wrong.

Answer 1

The formula for the area of a regular pentagon with side length "s" is:

A = (1/4) * √(5(5 + 2√5)) * s^2

Substituting s = 5 into the formula, we get:

A = (1/4) * √(5(5 + 2√5)) * 5^2
A ≈ 59.8

Rounding to the nearest tenth, the area of the regular pentagon is approximately 59.8 square units.
