`115` `dm^2 = ...11500...cm^2 `

`32000` `cm^2 = ......320....... dm^2`

`34` `dm^2` `12` `cm^2 = ........3412........cm^2 `

`->` `3400` `cm^2 + 12` `cm^2=3412` `cm^2`

`46000` `dm^2 = .....460....... m^2`

`5` `m^2` `28` `cm^2 = ...50028.........cm^2 `

`->` `50000` `cm^2+28` `cm^2=50028` `cm^2`

`3170` `cm^2 = ......31.....dm^2 ...7....... cm^2`
