[GRASS-user] does v.report fail?

Hi List,
running v.report I found an error in calculating Area (km^2). In my data it gives me a value of 3.33 km^2 while v.what gives: Sq Meters: 32942069.000 (33 km^2). I know that the correct answer is v.what (i know the area value).
Thank you

if possible, please provide an example with the North Carolina data set.
Which projection are you using?

I'm sorry.
