Answer:
Step-by-step explanation:
in all the question we have to use same technique
in 1 question
weight/force exerted by dorje(F)=1500N
total surface area of sole(A)=0.5m²
we know that,
P=

or, p=

∴ P=3000pa
in question 2nd
pressure(P)=40 pa
force exerted by block(F)=80N
we know,
pressure(P)=

area=

∴area =2m
ow you can do other by yourself
