Expert Answer
area is a vector because as u know pressure=force/area which is scalar"pressure"=vector"force" / X"area" area"X"= force/pressure which is vector/scalar =vector so area is a vector
In geometry, for a finite planar surface of scalar area S, the vector area
is defined as a vector whose magnitude is S and whose direction is perpendicular to the plane, as determined by the right hand rule on the rim (moving one's right hand counterclockwise around the rim, when the palm of the hand is "touching" the surface, and the straight thumb indicate the direction).
