Force = mg
= 6 × 9.8
= 58.8 N
(i) Area = 50 × 30
= 1500 cm²
Pressure = F/A
= 58.8/1500
= 0.039 Pa
(ii) Area = 30 × 20 = 600 cm²
Pressure = 58.8/600
= 0.098 Pa
= 6 × 9.8
= 58.8 N
(i) Area = 50 × 30
= 1500 cm²
Pressure = F/A
= 58.8/1500
= 0.039 Pa
(ii) Area = 30 × 20 = 600 cm²
Pressure = 58.8/600
= 0.098 Pa

For taking out pressure you have to use the formula P= F/A where P is pressure , F is force and A is the area. So you have got the area with you , just you need to find force
