42 dm = 420 cm

2 m 25 cm = 225 cm

25 m = 2500 cm

2 dam 12 m = 3200 cm

750 mm = 75 cm

7 m 2 dm = 720 cm

120 dm = 1200 cm

102 m = 10200 cm

35 mm = 3.5 cm

1 dam 2m = 1200 cm

42dm=420cm

2m=200cm
200cm+25cm=225cm

2m25cm=225cm

25m=2500cm

2dam=2000cm
12m=1200cm
2000cm+1200cm=3200cm

2dam12m=3200cm

750mm=75cm

7m=700cm
2dm=20cm
700cm+20cm=720cm

7m2dm=720cm

120dm=1200cm

102dm=1020cm

35mm= 3,5cm

1 dam=1000cm
2m=200cm
1000cm+200cm=1200cm

1dam2m=1200cm

Bonne soirée.
