The ratio of the areas of two similar sundeck porches is 225:36. If the larger sundeck is 15 feet along one side, how long is the smaller sundeck along its corresponding side? 6 feet 8 feet 10 feet 12 feet

OpenStudy (e.cociuba):

The answer to this is 6 feet. This is because 225 is 15^2, and 36 is 6^2. The second one is c, 155 because 93/1.8=51 1/3, and that times 3 is 155.
