Viết số thích hợp vào chỗ chấm :
| k m 2 | h m 2 | d a m 2 | m 2 | d m 2 | c m 2 | m m 2 |
| 1 k m 2 =.... h m 2 | 1 h m 2 =... d a m 2 =... k m 2 | 1 d a m 2 =... m 2 =.. h m 2 | 1 m 2 =100 m 2 =0,01 d a m 2 | 1 d m 2 =... c m 2 =... m 2 | 1 c m 2 =... m m 2 =... d m 2 | 1 m m 2 =.. c m 2 |
Chú ý : Khi đo diện tích ruộng đất người ta còn dùng đơn vị héc-ta (ha)
1ha = … m 2
