    Calculate the total walking distance required for maintenance workers to complete a full inspection circuit around a transit vehicle positioned in a pentagon-shaped inspection zone, where each side of the zone measures the same length in meters. The walking path follows the perimeter of the inspection zone to ensure systematic coverage of all vehicle checkpoints.
