What is the length of BC¯¯¯¯¯¯¯¯
 in centimeters?
A.10
 cm
B.12
 cm
C.20
 cm
D.21
 cm

To find the length of \( BC \) in pentagon \( ABCDE \) given that pentagons \( JKLMN \) and \( ABCDE \) are similar, we need to know the ratio of similarity. The length of \( BC \) can be calculated using this ratio.

Assuming we know the lengths of the corresponding sides of the pentagons, the formula to find the length of \( BC \) is:

\[
\frac{\text{Length of BC}}{\text{Length of corresponding side in JKLMN}} = \text{Ratio of similarity}
\]

If you provide the lengths of the corresponding sides or the ratio of similarity, I can help you determine the length of \( BC \).

### Do you have the lengths of the corresponding sides or the ratio of similarity?

### Here are some related questions to consider:
1. What are the lengths of the sides of pentagon \( JKLMN \)?
2. What is the ratio of similarity between the two pentagons?
3. Are there any other known side lengths in pentagon \( ABCDE \)?
4. Can you provide the angles of both pentagons?
5. Is there a specific context or application for this problem? 

### Tip:
When dealing with similar figures, always identify the ratio of similarity to simplify calculations for corresponding sides.
