Answer 1

[Cao Minh Tâm]

3 d a m 2   =   300   m 2           2 d a m 2   90 m 2 =   290 m 2

15 h m 2   =   1500 d a m 2             17 d a m 2 25 m 2   = 1705 m 2

500 m 2 = 5 d a m 2             20 h m 2   34 d a m 2 = 2034 d a m 2

7000 d a m 2 = 700   000 m 2           892 m 2   = 8 d a m 2 92 m 2
