I have a sheet of paper with a grid drawn on it, filling the whole paper. This grid has 4 rows and 9 columns, forming 36 congruent rectangles. Also, each of these rectangles is similar in proportion to the whole sheet.

If the sheet is 15 inches wide, how long is it?

(In reply to answer by logischer Verstand)

You seem to have used a method which ignores the similararity of the rectangles and tries to find what the proportions would be if the rectangles were squares.
