Explanation:
Pressure can be calculated through a simple equation according to which: P=F/A. Now Pressure is given as 50000 Pa and force=100 N, therefore Area= 100N/50000Pa = 1/500 square metres or 0.01 square metres.

Pressure = Force/Area
50000 Pa=100/ area
Area= 100/50000
Area=1/500
1/500 can be also said as 2/1000.
Area=2/1000 =2×10^-3
