[GRASS-user] the area of a polygon?

[Corrado]

Dear friends,

1) v.report does not allow for selecting only one polygon in a map with many 
polygons.

2) the query button returns the length of the boundary, but not the area. 

3) v.to.db does not allow for selecting only one polygon.

Am I doing something wrong?
