Hey there !!!
1m=100cm
1/100m=1cm
Area = 20*10cm²= 200* (1/100)²m²
=200/10000
=2/100
=0.02
Pressure = Force / Area
=70/0.02
=70/0.02
=7000/2
=3500 Pascal .
hope helped !

sanasubhani12ourwhq:
'=70/200 ^10-2' In this line, what do you mean by '^' and why did you subtract 2 from 10?
ur ans is wrong de

Me?
no....praneeth's
But I didn't answer anything. Oh..sorry. It was meant for Praneeth I guess.

Area = 20*10 cm²= 200cm² = 0.02 m²
P = F/A
= 70N / 0.02m²
=3500 N/m2
= 3500 Pa
P = F/A
= 70N / 0.02m²
=3500 N/m2
= 3500 Pa
Why did you turn 200 cm2 into a decimal number??
bcoz Pa is N/m²
not N/cm²
Ah! I get it I get it. Thanks, buddy!
welcome frnd
