The correct Answer is:
To find the area of triangle BOD when O is the centroid of triangle ABC, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Properties of the Centroid**: The centroid (O) of a triangle divides it into six smaller triangles of equal area when medians are drawn from each vertex to the midpoint of the opposite side. 2. **Identify the Area of Triangle ABC**: We are given that the area of triangle ABC is 96 cm². 3. **Calculate the Area of Triangle BOD**: Since the centroid divides triangle ABC into six smaller triangles of equal area, the area of triangle BOD will be one-sixth of the area of triangle ABC. \[ \text{Area of } \triangle BOD = \frac{\text{Area of } \triangle ABC}{6} \] 4. **Substitute the Given Area**: Now, substitute the area of triangle ABC into the equation. \[ \text{Area of } \triangle BOD = \frac{96 \text{ cm}^2}{6} \] 5. **Perform the Division**: \[ \text{Area of } \triangle BOD = 16 \text{ cm}^2 \] ### Final Answer: The area of triangle BOD is **16 cm²**. ---
