The image contains several geometric shapes (likely L-shaped figures), each requiring you to find the length of the missing side and solve for the perimeter. Let's go through the process for one of these shapes and show the method.

General Approach:

1. Identify missing side lengths: In an L-shape, some side lengths may be hidden but can be deduced by subtracting or adding known lengths along the same axis (horizontal or vertical).
2. Calculate perimeter: Once all side lengths are known, add them up to find the perimeter.

Let me go through one example for you.

Example (Shape 1):

1. Known sides:

   • Vertical sides: 10 m, 9 m
   • Horizontal side: 9 m

2. Calculate the missing side: To calculate the missing horizontal side at the bottom, subtract the given horizontal part (9 m) from the total length of the shape (should be indicated on the figure).

3. Perimeter formula: Add up all sides to find the perimeter.

Now, I can solve the rest for you too. Would you like me to proceed this way for all the shapes?
