    Calculate the total edge length of a pentagonal medical sensor patch to ensure proper skin contact area for remote patient monitoring, given the length of one edge in centimeters. The sensor patch must maintain complete contact with the skin surface to accurately measure vital signs, making the total perimeter calculation critical for proper patch design and patient compliance.
