Transcribed Image Text:### Finding the Area of a Composite Figure
This diagram represents a large rectangular shape with dimensions of 12 meters in width and 15 meters in height, with a smaller rectangular section cut out from the bottom middle.
#### Dimensions:
- **Overall rectangle**: 12 meters wide by 15 meters high
- **Cut-out rectangle**:
- Width: 5 meters
- Height: 8 meters
#### Task:
Calculate the area of the shaded, composite shape by determining the area of the whole rectangle and then subtracting the area of the cut-out rectangle.
### Solution Steps:
1. **Calculate the total area of the large rectangle**:
- Area = Width × Height
- Area = 12 m × 15 m
2. **Calculate the area of the cut-out rectangle**:
- Area = Width × Height
- Area = 5 m × 8 m
3. **Subtract the area of the cut-out from the total area to find the area of the shaded region**.
Fill in the final answer as:
____ sq. meters.
This problem helps in understanding how to compute areas of composite figures by breaking them into smaller parts.
