Description
In this exercise, you’ll create a form that accepts the length and width of a rectangle from the
user and then calculates the area and perimeter of the rectangle. 1. Start a new project named AreaAndPerimeter.
2. Add labels, text boxes, and buttons to the default form and set the properties of the form
and its controls so they appear as shown above. When the user presses the Enter key, the
Click event of the Calculate button should fire. When the user presses the Esc key, the
Click event of the Exit button should fire.
3. Create an event handler for the Click event of the Calculate button. This event handler
should get the values the user enters for the length and width, calculate and display the
area (length x width) and perimeter (2 x length + 2 x width), and move the focus to the
Length text box. It should provide for decimal entries, but you can assume that the user
will enter valid decimal values.
4. Create an event handler for the Click event of the Exit button that closes the form.
5. Test the application to be sure it works correctly. Accumulate test score data
