The question above makes use of the concept of ratio and proportion in a form of scaling. If we let x and y be the true length and width, the equations that best describe them are,
                                 0.5 cm / 1 inch = 2.5 cm / x in    ; x = 5 in
                                 0.5 cm / 1 inch = 4.75 cm / y in   ; y = 9.5 in
Therefore, the true length and width of Rueben's flag is 5 in and 9.5 in, respectively.
