Cho hỏi là 236901=.................m2.................dm2 vậy ạ
6km2 23456m2=…km2…hm2…dam2…m2=…km2

57932cm2=…m2…dm2…cm2=…m2
5,405m2=…m2…dm2…cm2=…cm2…=…dm2
a) 6km2 23456m2 = 6km2 23hm2 45dam2 6m2 = 6,23456km2
b) 5km2 246dam2 = 5km2 24hm2 6dam2 = 5,246km2
c) 57932cm2 = 5m2 79dm2 32cm2 = 5,7932m2
d) 5,405m2 = 5m2 40dm2 5 cm2 = 54050cm2 = 540,5dm2
