Efficiency= Work done/Q
W= 1/2 × 2T×S (Area of triangle)
   =T×S
Q= 1/2× 4t × S (Area of trapezium formed)
   =2T×S
Efficiency= W/Q ×100%
                  = 1/2×100
                  =50%

Dear student,
Please find the answer to your question.
 
Efficiency = Work done/Q(Heat gained)
W = 1/2 × 2To ×So (Area of triangle)
    = To × So
Q = 1/2× 4To × So (Area of trapezium formed)
    =2To × So
Efficiency= W/Q × 100%
                  = ½ × 100
                  = 50%
 
Thanks and regards,
Kushagra
