which block to be used for giving input to a function with a delay of few seconds, as step input block in sources is not giving the delay

Try using the Waveform Generator block with Waveform Definition parameter set to pulse with appropriate parameters. However, the Waveform Generator block does not accept a continuous sample time.

If you need the pulse to have continuous sample time, then you can use two step blocks. Set the 'Final value' of each to 0.1. Set the start time of the first to 1. Set the start time of the second to 1.1. Use a Subtract block to subtract the second from the first. The output of the Subtract should be the desired rectangular pulse.
