Question

3m² 21dm²=....dm²

1km² 500000m²=....m²

2km² 345m²=.....m²

 

Answer 1

3m2 21dm2=...321....dm2
1km2 500000m2=.....1500000..m2
2km2 345m2=....2000345......m2

Answer 2

3m2  21dm2=321dm2

1km2  500000m2=1 500 000m2

2km2  345m2=2 000 345m2

Answer 3

`3m^2  21dm^2 = 3xx100 + 21=321dm^2`

`1km^2 5500000m^2 = 1xx1000000 + 500000 = 1500000  m^2`

` 2km^2 345m^2 = 2xx1000000 + 345 = 2000345 m^2`
