Question

If 400 pa of pressure is applied to an area of 55 m^2, which is the resulting force

Answer 1

Since Pressure = Force/Area, to find the force you take Pressure * Area.

Then check your units. 1 Pa = 1N/M^2

Answer 2

Above solution is correct!

Answer 3

Same thing i m telling
Use
p=F/A
F=pA=?

Answer 4

Pressure = Force / area, which means Force = pressure x area.
Force = 400×55 = 22000N
