No, because your CSquare class still has no idea what that type T is going to be. What types of values do you want to store as height and width?

Seems pretty reasonable to me. You aren't guaranteeing that height or width are Numbers, so you can't multiply them.

Start out by converting the program to English. What does it do? Break it down into small steps- as small as possible. Then convert that to a Java program.
