Area Compound Rectangles F72Abd
1. **Problem Statement:** Calculate the area of a compound figure made up of five rectangles with given dimensions.
2. **Approach:** The total area of the compound figure is the sum of the areas of the individual rectangles.
3. **Identify Rectangles and Dimensions:**
- Bottom rectangle: width = 15 m, height = 6 m
- Left rectangle above bottom: width = 8 m, height = 5 m
- Middle lower rectangle above bottom: width = 5 m, height = 5 m
- Top small rectangle above middle: width = 2 m, height = 2 m
- Right rectangle height total = 13 m, so height above bottom rectangle = 13 m - 6 m = 7 m (this is the combined height of the two stacked rectangles on the right side)
4. **Calculate Areas:**
- Area of bottom rectangle: $$15 \times 6 = 90$$
- Area of left rectangle: $$8 \times 5 = 40$$
- Area of middle lower rectangle: $$5 \times 5 = 25$$
- Area of top small rectangle: $$2 \times 2 = 4$$
5. **Check for Overlaps:** The top small rectangle is part of the middle right stack, so the middle lower rectangle and top small rectangle are stacked, their combined height is $$5 + 2 = 7$$ which matches the right side height above bottom.
6. **Sum of all areas:**
$$90 + 40 + 25 + 4 = 159$$
7. **Final Answer:** The area of the compound figure is **159 square meters**.
