   | The difference between the ares of two rectangles | 2016-06-09 | 
  |  | Ingrid pose la question : I am trying to help my son with an area question.
 I have the answer, from the solutions, but I cannot figure out how to teach him.
 
 Question:
 
 Two rectangles have lengths 13cm and 19cm respectively.
 Their total area is 376cm squared.
 If both their widths are whole numbers, what is the difference in their areas?
 
 I know that this is solvable once I determine the widths of the rectangles ,
 but how do I go about finding that?
 
 Thanks for your help
