The two triangles BQA and DQC are similar triangles. The ratio of corresponding sides of similar triangle is the same.

So, we can write:

BQ : BA = DQ : DC
15 : 32 = DQ : 19.2
⇒
32 * DQ = 19.2 * 15

DQ = 9

We are to find the length of BD.

BD = BQ + QD = 15 + 9 = 24

So the answer to this question is 24
