    Design an algorithm for an automated grading system that calculates the total boundary length of a student's drawn pentagon shape when given the length of one side, to verify if their answer matches the system's calculation. The system needs to evaluate the perimeter calculation to provide instant feedback on the student's understanding of regular pentagon properties.
