    Design an algorithm to calculate the total security coverage area of a bank's fraud detection system, where the system forms a regular polygon pattern with 's' verification checkpoints and 'l' units of security intensity between each checkpoint. The coverage area represents the system's overall fraud detection capacity, which is essential for assessing the effectiveness of the bank's security framework.
