Help to get me going
Hi guys can you help me with abit of code for the following senario

Calculate area and perimeter


The user enters values for the length and width of a rectangle and clicks on the Calculate button or presses the Enter key to activate the Calculate button.
The application then displays the area and perimeter of the rectangle in two labels.

The formula for calculating the area: width * length.
The formula for calculating the perimeter: 2 * width + 2 * length.
The application should accept fractional decimal values like 10.5 and 20.65 for the user entries.
Assume that the user will enter valid numeric data for the length and width.

Add a Clear button to the form that will clear all of the values when you click on it.
Add numeric formatting and data validation.
Add exception handling.

It's a quite simple program.

Before spoon-feeding the solution, can you tell us how much have you progressed ?
