pressure is Force/Area
area = 0.02m²
pressure = 30/0.02= 3000/2=1500 Pa
area = 0.02m²
pressure = 30/0.02= 3000/2=1500 Pa

Pressure = Force/Area
Pressure is N/m^2, so we need to convert the area.
100cm = 1m
20cm = 20 x1/100 = 0.2m
10cm = 0.1 m
Area = length x breadth = 0.02m^2
P = (30/0.02) Pa
= 30 x 100/2 = 1500 Pa <=Answer
Thanks.
