    Calculate the total service coverage area of a delivery zone bounded by equal-length street segments, where 's' represents the number of connected street segments forming the zone boundary and 'l' represents the standardized length of each street segment in meters. This calculation is essential for optimizing delivery fleet distribution and determining resource requirements for the service area.
