1. **State the problem:** We need to find the area of an irregular L-shaped playground with given side lengths. 2. **Understand the shape:** The playground can be divided into two rectangles: - Rectangle 1 (left side): width = 3 m, height = 7 m - Rectangle 2 (right side): width = 9 m - 3 m = 6 m, height = 4 m 3. **Formula for area of a rectangle:** $$\text{Area} = \text{width} \times \text{height}$$ 4. **Calculate area of Rectangle 1:** $$3 \times 7 = 21$$ 5. **Calculate area of Rectangle 2:** $$6 \times 4 = 24$$ 6. **Add the two areas to get total area:** $$21 + 24 = 45$$ 7. **Final answer:** The area of the playground is **45 square meters**. Therefore, the correct choice is C 45.
