Author's name 2. Date 3. Purpose of the program Add more comments as needed D Create four functions in your script 1. calcRectangle Area0 Gets the values from the screen. It calculates the area of the rectangle, and RETURNS a value. 2. displayRectangle Area0 Calls calcRectangle Area0. Then, it displays the value on the screern. 3. calcTriangleArea Gets the values from the screen. It calculates the area of the triangle, and RETURNS a value. 4. displayTriangleArea0 Calls calcTriangle Area). Then, it displays the value on the screen. D Please pay attention to all bold RETURN words D Add comments for each function to explain what it does D Do not use any global variables, All variables must be local D You must follow naming conventions This might help 1. Use asterisk (*) as multiplication operator 2. Use slash (/) as division operator 3. This line of code in JavaScript gets the value from the textbox on the screen.

This line of code adds the value to the screen: frmCalculator ttAreavalue "Rectangle: "+ area
