Pressure is the force applied perpendicular to a surface divided by the area of the surface. Therefore, from the given values, we can easily calculate the area by dividing the force to the pressure. We do as follows:

Area = F / P

Area = 15000 / 190000

Area = 0.0789 m^2

Hope this answers the question. Have a nice day.
