  5. * COMPARE RECTANGLE AREAS 
  6. *____________________________________________________________________________________
  7. * This program asks the user to enter the length and width of two rectangles. The
  8. * program calculates the area of each rectangle and determines which rectangle has
  9. * the larger area, or if both rectangles have the same area.
  10. *
  11. * Rectangle Area Formula:
  12. * Area = Length x Width
  13. *____________________________________________________________________________________
  14. * INPUT
  15. *	length1 : Length of Rectangle 1
  16. *	width1  : Width of Rectangle 1
  17. *	length2 : Length of Rectangle 2
  18. *	width2  : Width of Rectangle 2
  19. *
  20. * OUTPUT
  21. *	area1   : Area of Rectangle 1
  22. *	area2   : Area of Rectangle 2
  23. *	Displays which rectangle has the greater area
