When it is complete, the program will ask the user to enter

the width and length of a rectangle and then display the rectangles area.

The program calls the following functions, which have not been written:

getLength This function should ask the user to enter the rectangles length and

then return that value as a double .

getWidth This function should ask the user to enter the rectangles width and then

return that value as a double .

getArea This function should accept the rectangles length and width as argu-

ments and return the rectangles area. The area is calculated by multiplying the

length by the width.

displayData This function should accept the rectangles length, width, and area

as arguments and display them in an appropriate message on the screen.
