Cho hỏi là 236901=.................m2.................dm2 vậy ạ
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
\(47dm^2=0,47m^2\)
\(32dm^214cm^2=32,14dm^2\)
\(26cm^2=0,0026m^2\)
\(5cm^26mm^2=5,06cm^2\)
\(2015m^2=0,2015ha\)
\(7000m^2=0,7ha\)
\(1ha=0,01km^2\)
\(21ha=0,21km^2\)
\(3,61m^2=361dm^2\)
\(54,3m^2=54m^230dm^2\)
\(9,5km^2=950ha\)
\(6,4391ha=64391m^2\)
