1. **Stating the problem:** We are given a person's physical examination data including weight, height, and Body Mass Index (BMI or IMT in Indonesian). We want to verify the BMI calculation. 2. **Formula used:** BMI is calculated using the formula: $$\text{BMI} = \frac{\text{weight (kg)}}{\text{height (m)}^2}$$ 3. **Given data:** - Weight = 48 kg - Height = 1.55 m - Reported BMI = 20 kg/m² 4. **Calculate BMI:** $$\text{BMI} = \frac{48}{1.55^2} = \frac{48}{2.4025} \approx 19.98$$ 5. **Interpretation:** The calculated BMI is approximately 19.98, which rounds to 20 kg/m², matching the reported BMI. 6. **Conclusion:** The BMI value of 20 kg/m² is correct based on the given weight and height. This confirms the physical examination data is consistent for BMI calculation.
