Hey here is your answer ^_^
⭐ANSWER :
⭐We know pressure = force/area
~~~(a)~~~
Force due to the elephant = 40000 N
Area on the ground = 1000 cm2= 0.1 m2
Pressure due to the elephant = 40000/0.1 = 400000 Pa
~~~(b)~~~
Force due to the girl = 400 N
Area on the ground = 1 cm2= .0001 m2
Pressure due to the girl = 4000000 PA
Hope it helps you out ⭐^_^⭐
Thanks ⭐(^^)⭐
