Answer to Question #250434 in C# for nick

Question

Create a windows desktop application which can be used by a local gardening service to determine the amount due by customers.

Your program should request the user to input the approximate length and breadth of the lawn, and whether cleaning the flower beds are included. Your program should then calculate and display the amount due, which is R8 per square meter of lawn, and a fixed cost of R60 if the flower beds needs to be cleaned.
