The correct Answer is:
To solve the problem of determining the height of the mirror required for a man who is 1.4 meters tall to see his complete height, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Problem**: We need to find the height of a mirror that allows a man who is 1.4 meters tall to see his entire reflection. 2. **Use the Formula**: The height of the mirror required to see the full height of a person is given by the formula: \[ \text{Height of the mirror} = \frac{1}{2} \times \text{Height of the person} \] 3. **Substitute the Height of the Man**: In this case, the height of the man is 1.4 meters. So we substitute this value into the formula: \[ \text{Height of the mirror} = \frac{1}{2} \times 1.4 \text{ m} \] 4. **Calculate the Height of the Mirror**: \[ \text{Height of the mirror} = 0.7 \text{ m} \] 5. **Conclusion**: Therefore, the height of the mirror should be 0.7 meters for the man to see his complete height. ### Final Answer: The height of the mirror should be **0.7 meters**. ---
