Question Analysis  

The task is to find the ratio of the side lengths of two similar polygons, given their perimeters (21 units for the smaller, 56 units for the larger). The key is using the property that the ratio of side lengths equals the ratio of perimeters for similar polygons.  

Key Concept Explanation  

For similar polygons, the ratio of corresponding side lengths is equal to the ratio of their perimeters. If the perimeters are and , then
