I’m trying to solve a calculus optimization problem where I need to find the maximum possible area with a perimeter of 8. I think my variables are (x), (y), and the angle , but I’m getting stuck on how to set up the equations properly.

So far, I’ve tried expressing the perimeter in terms of the variables and thinking about how to write the area formula, but I’m not sure how to connect everything or reduce the number of variables. Could someone point me in the right direction or explain how to start setting up this type of optimization problem?
