Answer to Question #1581 in C# for CALEB ADEYMO
Question #1581
Want to write a C# progm creating a Rectangle class to have two variables length and width. Two constructors are needed, the default constructor should intialize length and width to 1.0 each. The second must pass in two values to initialize length and width. There must be six methods to do the following: SetLength,SetWidth,GetLength,GetWidth, GetArea, and GetPerimeter.The perimeter is the sum of all sides of a rectangle. Three instances of the Rectangle needs to be created. The first rectOne must use the se
