Hi to all,
I calculated the area of a shape file polygon with 2 different tools:
the standard one from field calculator and the other method using a plugin
"geometry calculator".
 Do you know why I obtained 2 different results?
10144312,54 square meter
10148071,71  square meter

I am using Qgis 3.10 with grass and in the plugin I set up to use CRS of
the project.

Thanks, Azzurra
