7,5 km + 7 hm + 7 dam = . . . m 1000m + 50hm + 4km = . . .km Tlng kasih tau jawabannya sama caranya ya

1.) 7,5 km = 7500m
7 hm = 700 m
7 dam = 70 m
7500+700+70=8,270m

2.) 1000m=1km
50hm= 5 km
1+5+4= 10 km

semoga bener... maaf kalo salah

1 km = 1000 m
1 hm = 100 m
1 dam = 10 m

(7,5×1000) = 7500
(7×100) = 700
(7×10) = 70
total = 8270 m

2. 10 km + 5 km + 4 km = 19 km
