[GRASS-user] Joining two polygons

[Luisa Peña]

Greetings
I have imported a Shapefile with a few polygons (areas) and I want to join
two of them. These two have different Sq Meters, Hectares, Acres, Sq miles,
same layer (Layer: 1); different category (5 and 7), same Driver, same
database, same table, different cat, same key column, same Id, and other
fields are different. How can I join them in a single area?
Thanks
Luisa
