    Calculate the total contact edge length of a pentagonal vital-sign monitoring patch to ensure proper skin coverage and adhesion during patient monitoring. Given the length of one side of the pentagonal medical sensor patch in centimeters, determine the complete perimeter to validate if the patch will maintain consistent contact with the patient's skin throughout the monitoring period.
