How will the pressure change if the area over which the entire pressure force is evenly distributed increases by 5 times?

The body pressure on the selected surface can be calculated using the formula:
P = F / S, where F is the force of pressure on the surface, S is the total surface area over which the entire force of pressure is evenly distributed.
Pressure before area change:
P1 = F / S1.
Pressure after area change:
P2 = F / S2, where S2 = 5S1.
P2 / P1 = (F / S2) / (F / S1) = S1 / S2 = S1 / 5S1 = 1/5.
Answer: The pressure will decrease by 5 times.
