This is quite simple.
Use ratios to get 20:28
(smaller polygon:larger polygon)
Which equals 4:7.
This means that any side lengths of the smaller polygon to the ratio of its congruent side lengths of the larger polygon equals 4:7.
The work is cut out for you, as we know that one side is 4, therefore the other is 7.
