The correct Answer is:
To find the area of a triangle when the base and height are given, we can use the formula for the area of a triangle: **Area = (1/2) × Base × Height** ### Step-by-Step Solution: 1. **Identify the Base and Height:** - Base (b) = 12 m - Height (h) = 8 m 2. **Substitute the Values into the Area Formula:** - Area = (1/2) × Base × Height - Area = (1/2) × 12 m × 8 m 3. **Calculate the Area:** - First, multiply the base and height: - 12 m × 8 m = 96 m² - Now, multiply by (1/2): - Area = (1/2) × 96 m² = 48 m² 4. **Conclusion:** - The area of the triangle is 48 m². ### Final Answer: The area of the triangle is **48 m²**.
