In RTT(round trip time),why do we need to calculate the transmission time? 

bcz-"round-trip delay time (RTD) or round-trip time (RTT) is the length of time it takes for a signal to be sent plus the length of time it takes for an acknowledgment of that signal to be received. "This time delay therefore consists of the propagation times between the two points of a signal."

According to me no need to include transmission time

RTT=time taken by a packet from sender to receiver +time taken by acknowledgement from  receiver to sender.

so by the link given, RTT=2*25=50 m sec

32 frames will take time of 32 m sec

so sender has to wait for time=RTT- 32 m sec = 50-32=18 msec
