Question

a, 7 km2 =         m2

8,5 ha =             m2

300dm2 =           m2

4ha  =            m2

30 dm2 =                    m2 

515 dm2 =                 m2

Answer 1

7km² = 7 000 000m²

8, 5ha = 85 000m²

300dm² = 3m²

4ha = 40 000m²

30dm² = 0, 3m²

515dm2 = 5, 15m²

Answer 2

a,7 km²=7000000 m²

8,5 ha=8500000m²

300 dm²=3 m²

4 ha=40000m²

30 dm²=0,3 m²

515 dm²=5,15 m²

Answer 3

7 km2 = 7 000 000 m2 

8,5 ha = 85000 m2 

300 dm2 = 3 m2 

4 ha = 40 000 m2  

30 dm2 = 0,3 m2 

515 dm2 = 5,15 m2 

Ủng hộ tui nha! ^.^ 

Answer 4

A/7km2=7000000m2

  8,5ha = 85000m2

  300dm2=3m2

  4ha=40000m2

  30dm2=0,3m2

  515dm2=5,15m2

Answer 5

7 km2 = 7000000 m2

300 dm2= 3m2

4 ha= 40000 m2

30 dm2= 0,3 m2

515dm2= 5,15m2
