We all know that the area of a triangle having consecutive sides as ##\vec { a }## and ##\vec { b }## has the area ##\frac { 1 } { 2 } | \vec { a } \times \vec { b } |## but what is the direction of that area vector? I mean if we consider ##\vec { a } \times \vec { b }## that will be one direction and if we consider ##\vec { b } \times \vec { a }## then that will be the opposite direction but as we know an vector always has a particular direction so how to specify the direction of the area vector in this case?
