    Design a function that calculates the coverage area of a customer's fraud detection pattern, where the pattern forms a regular polygon with 's' verification checkpoints and 'l' units of security intensity between each checkpoint. The resulting area represents the total protective coverage of the fraud detection system for a customer's spending profile.
