  5. * COMPUTE THE AREA OF TWO RECTANGLES AND COMPARE THEM
  6. * ____________________________________________________________
  7. * This program computes the area of two rectangles
  8. * and compares which rectangle has the greater area
  9. * or if the areas are the same.
  10. *
  11. * Computation is based on:
  12. * The user's input on the length and width
  13. * entered for each rectangle.
  14. * ____________________________________________________________
  15. * INPUT
  16. * lengthOne: Length inputed by user for rectangle one
  17. * widthOne : width inputed by user for rectangle one
  18. * lengthTwo: Length inputed by user for rectangle two
  19. * widthTwo : width inputed by user for rectangle two
  20. *
  21. * OUTPUT
  22. * areaOne  : Area of rectangle one
  23. * areaTwo  : Area of rectangle two

Area comparison of two rectangles
What is the length of the first rectangle? 
What is the width of the first rectangle? 
Area one: 450

What is the length of the second rectangle? 
What is the width of the second rectangle? 
Area two: 500

The second reactangle has a greater area then the first reactangle.
