a) 1m2 = 100dm2 = 10000cm2= 1000000mm2

1ha = 10000m2

1km2 = 100ha = 1000000m2

b)1m2 = 0,01dam2

1m2 = 0,0001hm2 = 0,0001ha

1m2 = 0,000001km2

1ha = 0,01km2

4ha = 0,04km2

Viết các số đo sau dưới dạng số đo có đơn vị là héc-ta:

a)  1 m²  =  100 dm²  =   10000 cm²  =   1000000 mm²

1 ha  =  10000 m²

1 km²  =   100 ha  =  1000000 m²

b)  1 m² =  0,01 dam²

1m²  =  0,000001 km²

1 ha  =   0,01km²

4 ha  =  0,04 km²

a) \(1m^2=100dm^2=10000cm^2=1000000mm^2\)

\(1ha=10000m^2\)

\(1km^2=100ha=1000000m^2\)
