One polygon has a side of length 2 feet. A similar polygon has a corresponding side of length 4 feet. The ratio of the perimeter of the smaller polygon to the larger is
It is 20:10. If you add 2 5 times or 2 times 5, you get 10. If you multiply 4 by 5, you get 20. Thats how you get your answer. Hope this helps, and good luck!
