1. **State the problem:** We have two rectangles stacked vertically. The top rectangle measures 2 units wide and 8 units tall. The bottom rectangle measures 2 units wide and 3 units tall. We need to find the area of the shaded region, which is the bottom rectangle. 2. **Formula for area of a rectangle:** The area $A$ of a rectangle is given by the formula: $$A = \text{width} \times \text{height}$$ 3. **Apply the formula to the shaded rectangle:** The shaded rectangle has width = 2 units and height = 3 units. 4. **Calculate the area:** $$A = 2 \times 3 = 6$$ 5. **Interpretation:** The area of the shaded region is 6 square units. **Final answer:** The area of the shaded region is $6$ units².
