Finding the area of the stage + help with a pully problem

[ronaldo]

I have attached pictures of the two problems, the first part of the pully problem is correct, IDK how to do the next. If possible, could you please include how to solve the problem and not just the answer (the answer only is fine too!). Thanks!
