Convert simulink model to a single transfer function

Hi,

Given my diagram below, how do i convert it into a single block with the equivalent transfer function ? I do not mind having the transfer function displayed on MATLAB's command window instead.

https://www.youtube.com/watch?v=MG4LqZLsrC0 does not work as i have undefined constants in my diagram. I would like to be able to convert it to a single transfer function for studies. I know it is easy to solve it on paper to convert it to a single TF but I am learning MATLAB and I would like to overcome this problem. Thanks.

Regards, Haziq
