### Mathematics - Geometry

#### Find the Perimeter and the Area of the Figure

**Instructions**:
Calculate the perimeter and the area of the given figure. Provide your answers in terms of π (pi) and to the nearest tenth where applicable.

**Figure 7 Description**:
- A half-circle (semicircle) with a radius of 12 miles.

#### Table for Calculation

| | Perimeter | Area |
|---|-----------|------|
| 7 | | |

**Steps for Calculation**:
1. **Perimeter of the Semicircle**:
- The perimeter of a semicircle includes the curved part plus the diameter.
- The formula for the perimeter of a semicircle is:
\[ P = \pi r + 2r \]
where $ r $ is the radius.
- Given: $ r = 12 $ miles.

2. **Area of the Semicircle**:
- The formula for the area of a semicircle is:
\[ A = \frac{1}{2} \pi r^2 \]
where $ r $ is the radius.
- Given: $ r = 12 $ miles.

#### Example Calculation:
- Using the provided radius, apply the aforementioned formulas to find the perimeter and area.

---
This exercise aims to help students practice calculating the perimeter and area of a semicircle, reinforcing their understanding of geometry formulas.
```

This text and table are designed to aid students in calculating the perimeter and area of a semicircle, explaining the steps and providing the necessary formulas.
