Area Vector

Area is a scalar quantity, but in some the problems, it is convenient to treat it as vector. A small area can be treated as planar. As normal to the plane specifies the orientation of plane, therefore, the direction of planar area vector is along its normal.

By convention, the vector associated with every area element of a closed surface is taken to be in the direction of the outward normal.
