Răspuns :
1 km=10 hm=>2000 hm=200 km (2000÷10=200)
1 km=100 dam=>9000 dam=90 km (9000÷100=90)
1 km=1000 m=>7000 m=7 km (7000÷1000=7)
2000 km+200 km+90 km+7 km=2297 km
2200 km+90 km+7 km=2297 km
2290 km+7 km=2297 km

1 km= 10 hm => 2000 hm = 200 km
1 km= 100 dam => 9000 dam = 90 km
1 km = 1000 m => 7000 m = 7 km
2000 km + 200 km + 90 km + 7 km = 2297
