In this exercise, you will complete the Rectangle Area application that you created in Exercise 4 in Chapter 2.
a. Use Windows to copy the Area Solution folder from the VB2017\Chap02 folder to the VB2017\Chap03 folder. Open the Area Solution.sln file contained in the VB2017\Chap03\Area Solution folder. You created a Planning Chart for this application in Chapter 2. Enter the three Option statements in the Code Editor window. One of the buttons in the interface should calculate and display the rectangle’s area in both square feet and square yards; use either a flowchart or pseudocode to plan the button’s Click event procedure. Code the procedure using variables. Display the calculated amounts with a comma (if necessary) and one decimal place. Save the solution and then start and test the application. 

b. Now professionalize your interface by coding each text box’s TextChanged and Enter event procedures. Save the solution and then start and test the application.
