Answer 3

It seems like you have provided two variables, P (perimeter) and a (side length), but you haven't specified what shape they belong to. To help you solve the problem, I need to know the shape for which you have given the values of P and a. Please provide more context or information about the shape, and I'll be happy to assist you further with the solution.
