Show steps please.

For part (a), look in your calculus book. I can almost guarantee that whatever book you have, this problem is worked out as an example. Only instead of being about a parking lot bordering a street, it will be in terms of a farmer who wants to enclose 3 sides of a rectangular field with fencing, while the fourth side of the field borders a straight riverbank.
This problem is "the classic" maximization problem. I find it amusing that it has now morphed into this new form: a sign of the urbanization of a nation that used to be primarily rural!
