a) 6m² 76 dm² = 600 dm² + 76 dm² = 676 dm²

b) 3dm² 15 cm² = 300 cm² + 15 cm² = 315 cm²

c) 3m² 2 dm² = 300 dm² + 2 dm² = 302 dm²

d) 8m² 4 cm² = 80 000 cm² + 4 cm² = 80 004 cm²

câu số 3 là 2m2 nha mik ấn nhầm

1)1500 cm2=15 dm2

2)3m2=300dm2

3)20.000 cm2=2m2

4)12m2 5dm2=1205dm2

học tốt nhé!

\(\frac{2}{8}km^23m^2=0,25km^23m^2=2500030000cm^2\)

\(\frac{2}{5}m^232dm^2=0,4m^232dm^2=7200cm^2\)

\(\frac{3}{8}km^224m^2=0,375km^224m^2=3750240000cm^2\)

\(\frac{2}{4}m^2321dm^2=0,5m^2321dm^2=37100cm^2\)
