1. **State the problem:** We need to find the area of a composite figure made by joining two rectangles.
2. **Identify the rectangles and their dimensions:**
- Bottom rectangle: width = 75 in, height = 15 in
- Top smaller rectangle (centered): width = 25 in, height = 10 in
- Two side rectangles (attached to bottom rectangle on either side of the top rectangle): each width = 25 in, height = 15 in
3. **Formula for area of a rectangle:**
$$\text{Area} = \text{width} \times \text{height}$$
4. **Calculate the area of each rectangle:**
- Bottom rectangle area:
$$75 \times 15 = 1125$$
- Top smaller rectangle area:
$$25 \times 10 = 250$$
- Each side rectangle area:
$$25 \times 15 = 375$$
5. **Calculate total area:**
The figure is composed of the bottom rectangle plus the top smaller rectangle plus the two side rectangles.
$$\text{Total area} = 1125 + 250 + 2 \times 375$$
6. **Simplify:**
$$2 \times 375 = 750$$
$$\text{Total area} = 1125 + 250 + 750 = 2125$$
**Final answer:**
$$\boxed{2125}$$ square inches
