No. That method (in the class we talked about off-list) should return
a CRS that you want to be the default for area calculations. You
convert the WGS84 coordinates into this projection. E.g. in the
previous example, with the AreaFromLatLons class, we used the South
America Albers Equal Area Conic projection.

Yes, in the example code the result is in square metres. The CRS you
choose for calculations defines the distance unit. If you look at the
WKT definition for the CRS used in the example you will see this:
// UNIT["Meter",1],
Hope that helps, but if you have more questions or code snippets that
you want to check please feel free to post them to the list - that's
what it is here for :)
