Remarks

The method calculates the area or length of the geometry on the surface of the Earth ellipsoid, for geometry defined in projected or geographic coordinate system. This method preserves the shape of the geometry in its coordinate system. This means the true area or length will be calculated for the geometry you see in the map. (What you see is what you get.)

The returned lengths and areas are expressed in the specified linear units and area units, if present, or in the units of the spatial reference. If AreaUnit and LengthUnit are not specified and the input spatial reference is a geographic coordinate system, then the lengths and areas are expressed in meters.
