You need to read the API doc for the Rectangle class and see what methods it has.method getDiagonal is undefined for the type Rectangle
The compiler is not finding the method: getDiagonal
You must use methods that are defined for the class, you can not use undefined methods.
What do you want the code to do? The volunteers are here to help you write your code and get it to work.
We do not write code for you. Figure out what you want to do, write the code to do it and if you have problems with it, copy the code here and post your questions about the problems you are having.
Be sure to copy and paste the full text of any error messages.
