Expert Answer:

Work is a scalar quantity as no direction is needed to represent it. moreover it is scalar product of two vectors (force and displacement ).

Pressure is a scalar quantity. Since pressure is the force acting on an area. it  does not have a direction.

Area bounded of velocity versus time graph represents the displacement.
