There sure is: GetPolygonArea() gives you the area of a polygon in current map
units.
If you need the area in kilometers, you can preface that command with
SetMapUnits("Kilometers").
And if you want to be certain to put things back the way you found them, you
can:
- use GetMapUnits() to get the current units;
- use SetMapUnits() to make the units kilometers;
- use GetPolygonArea() to get the area in kilometers; and
- use SetMapUnits() to put things back to the initial value yielded by
GetMapUnits().
