1mm2= .......cm2

8mm2= ......cm2

19mm2= ......cm2

1dm2= .......m2

7dm2= .......m2

34dm2= .....m2

Answer 1

[Chu Quyen Nhan]

1 mm2 = 1/100 cm2 

8 mm2 = 8/100 cm2 

19 mm2 = 19/100 cm2 

1 dm2 = 1/100 m2 

7 dm2 = 7/100 m2 

34 dm2 = 34/100 m2

Answer 2

[Hàn Tử Băng]

1mm² = \(\frac{1}{100}\) cm²

8mm² = \(\frac{8}{100}\) cm²

19 mm² = \(\frac{19}{100}\) cm² 

1 dm² = ^{\(\frac{1}{100}\)}m²

7 dm² = \(\frac{7}{100}\) m²

34 dm² = \(\frac{34}{100}\) m²
