To calculate the perimeter of a composite shape like the L-shaped figure in the image, you need to add up the lengths of all the outer sides of the shape. Here's a general guide on how to approach this:

### Steps to Calculate the Perimeter:

1. **Identify and List All the Outer Sides:**
   - Start by identifying all the outer edges of the shape. For an L-shaped figure, these will be the lengths of the sides that outline the entire shape.

2. **Assign Labels to Each Side (if not already labeled):**
   - Label each side if it isn't already labeled. This will help keep track of which lengths you have accounted for.

3. **Calculate the Lengths of Any Missing Sides:**
   - If any side lengths are missing, you may need to calculate them by subtracting or adding other lengths based on the given dimensions.

4. **Add Up All the Outer Lengths:**
   - Once you have all the side lengths, add them together to get the total perimeter.

### Example Calculation (based on the L-shape in the image):
Let’s assume the L-shaped figure has the following dimensions based on typical L-shaped configurations:

- Top horizontal side (left part): 4 units
- Vertical side (left part): 6 units
- Bottom horizontal side (left part): 2 units
- Top horizontal side (right part): 4 units
- Vertical side (right part): 2 units
- Bottom horizontal side (right part): 6 units

The perimeter \( P \) would be calculated as:

\[
P = 4 + 6 + 2 + 4 + 2 + 6 = 24 \text{ units}
\]

**Note:** This example uses typical dimensions, so ensure the exact numbers from your image are used.

If you provide the exact measurements or confirm the dimensions in your image, I can give a more precise solution!
