Question

1km2 = ....... ha

1ha = ........... m2 

7hm2 = ......... m2

12dam2 = .......... m2

3ha = ............ m2

1m2 = ..........dam2 = .......... ha

15m2 =............ dam2 =.............hm2

8000m2 =.............ha

1400cm2 =............m2

5ha=............ km2

Giúp mình nha! Thanks!

 

Answer 1

1 km 2 = 100 ha

1 ha = 10000 m2

7 hm2 = 70000 m2

12 dam2 = 1200 m2

3 ha = 30000 m2

1m2 = 0,01 dam2=0,0001 ha

15 m2 = 0,15 dam2=0,0015 ha

8000 m2 = 0,8 ha

1400 cm2 = 0,14 m2

5 ha = 0,05 km2

Answer 2

\(1km^2=100ha\)

\(1ha=10000m^2\)

\(7hm^2=70000m^2\)

\(12dam^21200m^2\)

\(3ha=30000m^2\)

\(1m^2=0.01dam^2=0.0001ha\)

\(15m^2=0.15dam^2=0.0015hm^2\)

\(8000m^2=0.8ha\)

\(1400cm^2=0.14m^2\)

\(5ha=0.05km^2\)
