1. **State the problem:** We need to find the total area of the two shaded faces of a cuboid. One face measures 7 cm by 9 cm, and the other measures 7 cm by 12 cm. 2. **Recall the formula for the area of a rectangle:** $$\text{Area} = \text{length} \times \text{width}$$ 3. **Calculate the area of the first shaded face:** $$7 \times 9 = 63 \text{ cm}^2$$ 4. **Calculate the area of the second shaded face:** $$7 \times 12 = 84 \text{ cm}^2$$ 5. **Add the two areas to find the total shaded area:** $$63 + 84 = 147 \text{ cm}^2$$ 6. **Final answer:** The total area of the two shaded faces is **147 cm²**.
