Answer 2

Answer:

T=1/2efficiency=output/input entropy (s)=Q/T after rearranging we getQ=S×T from above diagram it is clear that Q=area of triangle wich is equal to 1/2 S×T and efficiency is equal to heat given out by the system to the heat given to the system heat given to system=S×T heat given by system=1/2 S×T putting the values in formula we get efficiency=Q2/Q1 1/2S×T÷S×T
