1. **State the problem:** We need to find the combined area of the parallelogram and the triangle in the composite figure.
2. **Recall formulas:**
- Area of a parallelogram: $$\text{Area} = \text{base} \times \text{height}$$
- Area of a triangle: $$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$$
3. **Calculate the area of the parallelogram:**
Given base = 4 cm and height = 6 cm,
$$\text{Area}_{\text{parallelogram}} = 4 \times 6 = 24$$ cm$^2$
4. **Calculate the area of the triangle:**
Given base = 8 cm and height = 2.5 cm,
$$\text{Area}_{\text{triangle}} = \frac{1}{2} \times 8 \times 2.5 = \frac{1}{2} \times 20 = 10$$ cm$^2$
5. **Find the combined area:**
$$\text{Combined area} = 24 + 10 = 34$$ cm$^2$
**Final answer:** The combined area of the parallelogram and the triangle is **34 cm$^2$**.

Since the user also asked for the area of the composite figure (parallelogram + trapezoid + triangle), we calculate that as well:
6. **Calculate the area of the trapezoid:**
Given bases 8 cm and 4 cm, height 2.5 cm,
$$\text{Area}_{\text{trapezoid}} = \frac{1}{2} \times (8 + 4) \times 2.5 = \frac{1}{2} \times 12 \times 2.5 = 6 \times 2.5 = 15$$ cm$^2$
7. **Calculate total area of composite figure:**
$$\text{Total area} = 24 + 10 + 15 = 49$$ cm$^2$
