- 12
- 18
- 24
- 30

Hint:

### If a line is drawn parallel to any one side of a triangle so that it intersects the other two sides in two distinct points, then the other two sides of the triangle are divided in the same ratio.

## The correct answer is: 12

Hence, the correct option is D.

It is also called basic proportionality theorem.
