tlong di jawab dari nomor 14 - 18.... gunakan caranya ya....... plisssssss

15. 2 m = 200 cm
2500 mm = 250 cm
200 - 75 = 125 + 250 = 275 cm
=2,75 m

16. 30 menit = 30*60 = 1800 detik
1800*0,5 l/detik = 180*5 l/detik
= 900 liter

17. luas tanah =200 m ²
0,5 dam² = 50 m²
2500 dm² = 25 m²
200 - 50 - 25 = 125 m²

18.30 mnt = 1/2 jam
40 km/jam*1/2 jam = 20 km
