Question Analysis  

The task is to determine the ratio of the perimeters of two similar polygons given their side-length ratio (3:5). The key is recognizing that the perimeter ratio of similar polygons equals their side-length ratio.  

Key Concept Explanation  

For similar polygons, the ratio of corresponding side lengths is equal to the ratio of their perimeters. If the side-length ratio is , the perimeter ratio is also .  

Step-by-Step Solution  

1. Apply the similarity property:  

Given the side-length ratio
