Answer:

Explanation:
From the question we are told that:
Initial Pressure 
Initial Temperature 
Final Pressure 
Final Temperature 
Work Output 
Generally Specific Energy from table is
At initial state


With
Specific Volume 
At Final state


Generally the equation for The Process is mathematically given by

Assuming Mass to be Equal

Where



Therefore


Explanation:
He would work on the thing like in the method you work on your question.
Volume=Hh(b1+b2)/2. b1 and b2 are the base of the trapezoid
