Write a program with a custom, void method that determines the cost of painting the walls and door of a windowless, rectangular garage. One coat of paint will do it. The custom method does all of the work. The main method simply calls it. The custom method must prompt the user for the:

• Garage dimensions in feet.

• Cost of one can of paint.

• Area in square feet covered by one can of paint.

All inputs could have decimals. The method should print:

• Total cost of painting the garage.
