Question
the answer on here is giving me error each time i tried...Problem: The Westfield Carpet company has asked you to write a Visual Basic application that calculates the price of carpeting. To calculate the price of the carpet, you multiply the area of the floor (width x Length) by the price per square foot of the carpet. For example, the area of a floor this is 12 feet long and 10 feet wide is 120 feet to cover that floor with carpet that cost $8 per square foot would cost $960. You should create a class named rectangle with the following properties as doubles: width, length, Area. The area property should be read-only. Provide a method named CalcArea that calculates the x length and stores the result in the area property. Next, create a class named carpet with the following properties: Color (string), style (string) and price (double). The application should have a form similar to the one shown in the figure below. (the carpet price is the price per square foot.) When the calculate button is clicked, the application should copy the data in the text boxes into the appropriate object properties, and then display the area and price...use bisual basic
