a) 8 dam=80 m
46 m= 46 m
4 km =4000 m
16 km=16000 m
80 m+46m+4000m+16000m= 20126 m
b) 38 m= 0,38 hm
42 dam= 4,2 hm
7 hm= 7 hm
12 km =120 hm
0,38 hm + 4,2 hm +7 hm + 120 hm =
131,58hm
c) 16 m =1,6 dam
8 hm=80 dam
9 dam =9 dam
11 km = 1100 dam
1,6 dam + 80 dam + 9 dam + 1100 dam =
1190,6 dam
d) 5 dam = 0,05 km
60 m = 0,06 km
80 hm = 8 km
13 km = 13 km
0,05+0,06+8+13= 21,11 km
