It is given that 
and 
are the position vectors of vertices of a quadrilateral 
respectively. Let 
and 
are the middle points of sides 
and 
respectively. The position vectors of these points will be 
Then 
and 
It is clear that 
is parallel to 
and 
is parallel to 
. Thus 
is a parallelogram.
Area of parallelogram 
is,
