Question
**Activity: Calculating the Area of a Composite Figure**

**Task:**
Find the area of the composite figure.

**Diagram Explanation:**
The figure is a complex shape composed of multiple smaller geometric parts combined together. It consists of a larger L-shaped base and a smaller rectangular cut-out. The dimensions provided are as follows:

- The left side of the larger shape is 7 meters.
- The base of the larger shape is 4 meters.
- The upper right section of the shape has lengths of 5.2 meters horizontally and vertically, indicating a small rectangular cut-out.
- The bottom right section of the shape also has a 5.2-meter length.
- The small rectangular cut-out at the bottom measures 2 meters vertically.

**Instructions:**
1. Break down the composite figure into simpler shapes (e.g., rectangles and triangles).
2. Calculate the area of each shape.
3. Subtract the area of any cut-out sections from the total area of the larger shape.
4. Provide the answer in square meters.

**Note:**
Make sure to show each step of your calculation for full understanding and clarity. Remember, this is a required question, so be sure to fill in your answer before submitting your work.
