Answer 1

To calculate the area of the frame, we first need to find the area of the outer rectangle (the outside of the frame) and the area of the inner rectangle (the unpainted area inside the frame).

1. **Calculate the area of the outer rectangle:**
- Width = 9 ft
- Height = 12 ft
- Area (outer) = width × height = 9 ft × 12 ft = 108 ft²

2. **Calculate the area of the inner rectangle:**
- Width = 6 ft
- Height = 10 ft
- Area (inner) = width × height = 6 ft × 10 ft = 60 ft²

3. **Calculate the area of the frame:**
- Area (frame) = Area (outer) - Area (inner) = 108 ft² - 60 ft² = 48 ft²

Therefore, the area of the frame is **48 ft².**
