The sides of a polygon are 3, 5, 4, and 6. The shortest side of a similar polygon is 9. Find the ratio of their perimeters.

the shortest side of the polygon where all the sides are known is 3. since 9 is the shortest side of the similar polygon, we know that to obtain rest of the sides we must multiply each side by the same value, which will be 3 because 9/3 is 3. the similar polygon will have sides of 9,15,12, and 18. you can probably figure out the rest.
(3+4+5+6)/(9+12+15+18) =
1/3
