123.9 m²
12.4 m²
61.9 m²
49.5 m"

Answer 1

To answer the question being asked, we need the expression for the area of a regular pentagon. It is expressed as:

A=(1/4) (a²) (√5(5+(2√5))


A=(1/4) (6²) (√5(5+(2√5))
A = 61.94

Therefore, the correct answer from the list of choices is the third option.

Answer 2

Area of regular pentagon is 61.94 m². So, option 'C' is the correct answer to the following question.

Area of regular pentagon:

What information do we have?

Side of pentagon = 6 m

Area of regular pentagon = $\frac{1}{4\sqrt{5(5+2\sqrt{5} )}a^{2} }$

Area of regular pentagon = $\frac{1}{4\sqrt{5(5+2\sqrt{5} )}6^{2} }$
