Measure Results different

I created an Add-In tool, which insert a feature from Source FC (S) into a Target FC (T).  The inserted feature's SHAPE.AREA and SHAPE.LEN values are automatically calculated.  In my code, the Area value is also calculated as shown below:

   IArea area = f_Target.Shape as IArea;

   double d_Area = area.Area;

The results show that      d_Area / SHAPE.AREA = 4.10754

I used the Measure Tool and found that the  SHAPE.AREA  value is CORRECT. 

I could not figure out why the ArcObjects code is wrong.  Appreciate if you can help with your knowledge.
