A picture frame measures $14$cm by $20$cm. $160$cm$^2$ of the picture shows inside the frame. Find the width of the frame.

This is the question I was given, word-for-word. Is it asking for the width of the picture? Becuase the way I see it, the width is simply $14$...
EDIT: Is this the correct interpretation? (Sorry did a really quick drawing in MS paint, red represents what I am supposed to find)


The question pretty ambiguous.  My interpretation would be that you have a rectangular picture frame whose exterior dimensions are $14\times 20$.  The frame has uniform width, so all sides are the same width.  If you place a picture in the frame then $160$ square cm of the picture will be visible.  What is the width of a side of the frame?
