Answer:

The missing length = 30.

Step-by-step explanation:

Since the polygons are similar corresponding sides are in the same proportion So:

15/18 = 25/x

15 * x = 18*25

x =  18*25/15

= 30

Answer: 30

Step-by-step explanation:

These shapes are similar, which means their corresponding sides are proportional. A proportion will do nicely for this problem. 18/x=15/25. Cross multiplying 18 and 25 will give you a value that you can divide by 15 to get your answer.
