The uploaded image contains two mathematical tasks:

### Task 1: Decomposing and Composing Quadrilaterals and Triangles
1. **Draw Shapes and Label Dimensions**:
   - **Parallelogram**: Base \(b\), height \(h\)
   - **Triangle**: Base \(b\), height \(h\)
   - **Trapezoid**: Two bases (\(b_1\), \(b_2\)), height \(h\)

2. **Combine Areas**:
   - This part seems to ask for deriving formulas for the area of each shape.

### Task 2: Comparison of Triangle Areas
- Without calculations, determine which triangle has a greater area by looking at the provided graph and writing a sentence explaining the reasoning.

### Detailed Analysis:
- For Task 1, the formulas are:
  - **Parallelogram**: \( \text{Area} = b \cdot h \)
  - **Triangle**: \( \text{Area} = \frac{1}{2} b \cdot h \)
  - **Trapezoid**: \( \text{Area} = \frac{1}{2} (b_1 + b_2) \cdot h \)

- For Task 2, visually compare the triangles on the graph to see which one has a larger area based on their bases and heights.

Would you like more details on the solutions or any specific part of these tasks? Here are five questions related to the tasks:

1. How do we derive the area formulas for parallelograms, triangles, and trapezoids?
2. What properties of triangles help determine their areas without calculation?
3. How does the height of a shape affect its area?
4. Why is the area of a triangle half of that of a parallelogram with the same base and height?
5. How can we visually compare areas on a graph without calculating them?

**Tip:** Understanding the relationship between base and height in different shapes is key to calculating and comparing areas efficiently!

Draw each figure and then label a base and height. Then, use these labels to derive the formulas for the area of a parallelogram, triangle, and trapezoid. Without performing any calculations, determine which triangle has the greater area.

Understand how to derive area formulas for parallelograms, triangles, and trapezoids, and learn how to visually compare triangle areas based on graph representations. Ideal for students in Grades 6-8.
