java

The attached program is your starting point for this assignment. The Geometry.java program will compile, but when you run it, it doesnt appear to do anything except wait. That is because it is waiting for user input, but the user doesnt have the menu to choose from yet. You will need to create one per the following:

Above the main method, but in the Geometry class, create a static method called printMenu that has no parameter list and does not return a value. It will simply print out instructions for the user with a menu of options for the user to choose from. The menu should appear to the user as:

This is a geometry calculator, Choose what you would like to calculate:

Find the area of a rectangle

Find the perimeter of a rectangle

Find the perimeter of a triangle

Enter the number of your choice:

Add a line in the main method that calls the printMenu method as indicated by the comments.

Compile, debug, and run. You should be able to choose any option, but you will always get 0 for the answer. We will fix this in the next task.

Write a static method called rectangleArea that takes in the length and width of the rectangle and returns the area using the formula A = lw (ie. Length * width).

Write a static method called rectanglePerimeter that takes in the length and the width of the rectangle and returns the perimeter of the rectangle using the

formula P = 2l +2w.

Write a static method called trianglePerimeter that takes in the lengths of the three sides of the triangle and returns the perimeter of the triangle which is calculated by adding up the three sides.

Add lines in the main method in the Geometry class which will call these methods. The comments indicate where to place the method calls.
