## 📊 Rumus BMI
\[
BMI = \frac{berat\ badan\ (kg)}{(tinggi\ badan\ (m))^2}
\]

### Contoh:
Jika berat = 70 kg dan tinggi = 170 cm  
→ BMI = 70 / (1.7 × 1.7) = **24.22**

## 💡 Kategori BMI
| Rentang BMI | Kategori |
|--------------|-----------|
| < 18.5 | Kurus |
| 18.5 – 24.9 | Normal |
| 25.0 – 29.9 | Gemuk |
