    Calculate the total boundary length of a pentagonal emergency room waiting area to optimize patient flow and maintain social distancing requirements, given that all sides of the waiting area are equal in length. The boundary length will be used to determine maximum occupancy and establish proper distancing markers for waiting patients.
