Then you can definitely propose those changes through PRs. Please refrain from adding more activities as they are enough according to the time limit.

Hey @srishti-034 I have some ideas to improve activity1 like instead of creating methods like create area and display we can add one more method in abstract class like find area of rectangle square and triangle. How about changing it! Waiting for your reply

Hey @tejaswini22199 rectangle area has already been calculated in in RectangleArea class. So we need to make a new class for Triangle and override the calculateArea method accordingly.
I have used a single method just to illustrate the concept. You can further experiment with it but the idea which needs to be conveyed should remain simple, crisp and easy for learner to understand.
