all area in indonesia or all areas in indonesia ?.

which is correct? the first one or the second?...

Anonymous: Both are correct grammatically.
No, they are not.

The capitalisation is wrong for a start and 'All area in Indonesia' is ungrammatical.

'All areas of Indonesia' or 'The whole of Indonesia' are correct.
Both are correct grammatically. The choice of the singular or plural form depends on the context. If you think about Indonesia territory as a whole then "area" is the right word; if you mean territorial parts of the country the plural form is appropriate.
