1ha=...m2
1km2=...ha=...m2
b)1m2 = ...dam2
1m2 = ...hm2 =..ha

Bài 2:
Viết các số đo sau dưới dạng số đo có đơn vị là héc-ta:
a)65000m2 ; 846000m2 ; 5000m2
b)6km2 ; 9,2km2 ; 0,3km2.
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
