2 km^2 = m^2 3.000 are = hm^2 1,5 hektare = m^2 54 km/jam = m/detik 200 cm/detik = km/jam

2 km² = 2.000.000 m²
3.000 are = 30 hm²
1,5 hektare = 15.000 m²
54 km/jam = 54000/3600 = 15 m/detik
200 cm/detik = 0,2x3600 = 720 km/jam
     semoga membantu :)

1. 2 km² = m²
=> 2 km² = 2 x 1000000 m²
=> 2 km² = 2000000 m²

2. 3000 are = hm²  (cat: 1 are = 1 dam²)
=> 3000 are = 3000 : 100 hm²
=> 3000 are = 30 hm²

3. 1,5 hektare = m²
=> 1,5 hektare = 1,5 x 100 m²
=> 1,5 hektare = 150 m²

4. 54 km/jam = m/detik
=> 54 km/jam = 54 x 1000 m/jam
=> 54 km/jam = 54000 m/jam
=> 54 km/jam = 54000 : 3600 m/detik
=> 54 km/jam = 15 m/detik

5. 200 cm/detik = km/jam
=> 200 cm/detik = 200 : 1000 km/detik
=> 200 cm/detik = 0,2 km/detik
=> 200 cm/detik = 0,2 x 3600 km/jam
=> 200 cm/detik = 720 km/jam
