1. **Problem 1: Find the area of the irregular polygon (in inches).**
The figure is composed of a rectangle and a right triangle on top.
2. **Formula and rules:**
- Area of rectangle = length \times width
- Area of right triangle = \frac{1}{2} \times base \times height
3. **Calculate the area of the rectangle:**
- Given dimensions: length = 30 inches, width = 25 inches
- Area_rectangle = 30 \times 25 = 750 \text{ square inches}
4. **Calculate the area of the right triangle:**
- Given dimensions: base = 15 inches, height = 8 inches
- Area_triangle = \frac{1}{2} \times 15 \times 8 = \frac{1}{2} \times 120 = 60 \text{ square inches}
5. **Total area:**
$$\text{Area_total} = \text{Area_rectangle} + \text{Area_triangle} = 750 + 60 = 810 \text{ square inches}$$

6. **Problem 2: Find the perimeter of the L-shaped polygon (in centimeters).**
7. **Given:** All angles are right angles, side lengths 32 cm and 25 cm are labeled.
8. **Determine all side lengths:**
- The L-shape has 6 sides.
- Two sides are given: 32 cm and 25 cm.
- The other sides can be found by subtracting overlapping lengths.
9. **Calculate missing sides:**
- The vertical side adjacent to 25 cm is 32 - 25 = 7 cm
- The horizontal side adjacent to 32 cm is 25 - 7 = 18 cm
10. **List all sides:**
- 32 cm, 7 cm, 18 cm, 25 cm, 7 cm, 18 cm
11. **Calculate perimeter:**
$$\text{Perimeter} = 32 + 7 + 18 + 25 + 7 + 18 = 107 \text{ cm}$$
