3,5km-20hm+35dam =..........m

3,5km-20hm+35dam=..........m
3,5km=3500 m
20hm=2000m
35dam=350 m
3500-2000+350=1500+350=1850m
maaf klo kurang tepat

Maka karena ditanyakan satuan meter kita ubah dulu
3,5 Km = 3500 m
20 Hm = 2000m
35 Dam = 350m
jadi jawabannya
3500 m - 2000 m + 350 m =1850 Meter

thank you for asking!
