Pressure= \frac{Force}{Area}

So pressure is directly proportional to force and inversely proportional to area.
You can increase the pressure by changing either force or area or both.

a) If you want to increase pressure while keeping area unchanged,
you have to change force.
Since pressure is directly proportional to force, increase the force.

b) If you want to increase pressure while keeping force unchanged,
you have to change area.
Since pressure is inversely proportional to area,  decrease the area.

Pressure is equal to force per unit area so it is directly proportional to force and inversly proportional to area. so we can increase pressure by keeping area unchanged
