Answer:

SR = 28

Explanation:

Recall: The corresponding side lengths of any two similar polygons are proportional.

Since the two polygons given are similar, it implies that:

SR/DC = PQ/AB

SR = ?

DC = 20

PQ = 21

AB = 15

Plug in the values

SR/20 = 21/15

Solve for SR. Cross multiply

SR*15 = 21*20

SR*15 = 420

Divide both sides by 15

SR = 420/15

SR = 28
