If the perimeter of a semicircle is 36 cm, then find its area (in `cm^2`)

Options

A. 154
B. 35
C. 77
D. 70

Explanation

To solve the problem of finding the area of a semicircle given that its perimeter is 36 cm, we can follow these steps:

### Step 1: Understand the formula for the perimeter of a semicircle
The perimeter \( P \) of a semicircle is given by the formula:
\[ P = \pi r + 2r \]
where \( r \) is the radius of the semicircle. The term \( \pi r \) represents the curved part of the semicircle, and \( 2r \) represents the diameter.
