Paper of Rousseau

I need a paper of 3 pages about Rousseau book which I attached it down. Please  I need it in an easy language. Also please proof that you read and I need you to answer these questions in the paper1.     Why do we have states according to Rousseau? What is the essence of the concept of a “social contract”? How do we make sure our states will not enslave us? Do you agree with him?
