I would think you would want to consider the "worst case" situation when determining an
antenna wind area.  If the worst case is when the elements are broadside to the wind,
then you would want to consider ALL of the element wind area.  If the worst case is when
the boom is broadside to the wind, then you would want to consider ALL of the boom
area.  One or the other will be the real "worst case".  If you take half of one and add
it to half of the other, you result will be somewhat LESS than the real worst case, it
seems to me.
