    Design a function that calculates the total boundary length of a suspicious transaction pattern grid, where each side represents a standardized transaction amount range in the fraud detection system. The function should take the length of one standardized transaction range as input and return the complete boundary measurement needed to monitor the entire square pattern of potentially fraudulent activities.
