ANY LENGTH on the DVD cover is (1/6) of the SIMILAR measure on the poster.
4.5 ft * 12 in/ft = 54 inches on the poster
then
54/6 = 9 inches on the DVD
The image on a movie poster was shrunk to make the DVD cover art for the movie, so that the cover art is a scale image of the poster. The poster is 36 inches wide, and the DVD cover art is 6 inches wide. If the diagonal of the poster is 4.5 feet, what is the diagonal of the DVD cover art?
12 inches
9 inches
0.67 inch
7 inches

posterwide/dvdwide=posterdiagonal/dvddiagonal
36/6=4.5/dvdwide
divdwide= 4.5*6/36
36/6=4.5/dvdwide
divdwide= 4.5*6/36
