Subject: [geometry] Ring intersection question

Hi all,

I have a question regarding the intersection of ring concepts using
Boost.Geometry. I currently have two overlapping rectangles defined by the
following WKTs:

POLYGON((75 75,75 175,275 175,275 75,75 75))
POLYGON((50 50,50 150,250 150,250 50,50 50))

When I perform the intersection of these rectangles, I get the intersection

POLYGON((75 150,250 75))

The intersection points do not allow me to compute the area correctly after
the intersection. Is there way to get a fully valid ring/polygon out of
intersection, so that the area will be equal to the overlapping region?
