To find the perimeter of this figure, we need to calculate the perimeter of each part and then sum them up.

### Breakdown of the Shape
The figure seems to consist of:
1. Two vertical straight sides, each 18 meters in length.
2. One horizontal straight side at the bottom, 6 meters in length.
3. A semicircular arc at the top, which seems to be part of a circle with a diameter equal to the width of the shape (6 meters).

### Step-by-Step Calculation

1. **Straight Edges**: 
   - The two vertical sides are each 18 m, so \( 2 \times 18 = 36 \) meters.
   - The bottom side is 6 m.

2. **Semicircular Arc**:
   - The diameter of the semicircle is 6 m, so the radius \( r = \frac{6}{2} = 3 \) meters.
   - The circumference of a full circle with this radius would be \( 2 \pi r = 2 \times 3.14 \times 3 = 18.84 \) meters.
   - Since we only have a semicircle, we take half of this: \( \frac{18.84}{2} = 9.42 \) meters.

3. **Adding All Parts Together**:
   - Total perimeter = \( 36 + 6 + 9.42 = 51.42 \) meters.

### Final Answer:
The perimeter of the figure is **51.42 meters**.

### Tip
When calculating the perimeter of complex shapes, break them down into simpler components (like straight lines and arcs) for easier computation.
