Question

Why is the pressure less and the area high and the pressure high and area low whereas the force high and the pressure high

Answer 1

high area have Blunt surface where low area have sharp surface

Answer 2

Thrust acting on unit area is called pressure.
In other words,
Pressure is defined as the force acting perpendicular on unit area of the surface.

P = F / A

SI unit is Pascal ( Pa )

We also know that,

Pressure acting on the surface is inversely proportional to the area of the surface in which force acts

Pressure is directly proportional to the applied force.
