3 km² + 4 hm² = ...dam² tolong dibantu,, caranya simpel aja yah.. pake cara

Mapel : Matematika
Bab : Pengukuran

Diketahui :
- 3 km² = 3 × 10.000 dam² = 30.000 dam²
- 4 hm² = 4 × 100 dam² = 400 dam²

Ditanya :
- 3 km² + 4 hm² = .....dam²?

Penyelesaian :
3 km² + 4 hm²
= 30.000 dam² + 400 dam²
= 30.400 dam²

Maaf Kalau Salah

3 Km² = 30.000 Dam²
4 Hm² = 400 Dam²
= 3 Km² + 4 Hm²
= 30.000 Dam² + 400 Dam²
= 30.400 Dam²
