    Calculate the total boundary distance of a pentagon-shaped delivery zone to determine optimal route coverage for delivery drivers during peak hours, given the length of one zone boundary segment. The delivery zones are divided into regular pentagon sectors to ensure balanced distribution of deliveries across the service area.
