Answer 2

Answer:

9^2/4^2 = 81/16

Step-by-step explanation:

Theorem: If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides. This proves that the ratio of the area of two similar triangles is proportional to the squares of the corresponding sides of both the triangles.

so you just need to prove that the both triangles are similar

In order to prove any two triangles are similar you prove only two pairs of angles has the same measure

1. they share one angle B

2. the triangle ABD has the angle D=90 same as the triangle PBQ has the angle Q=90

THEREFORE THEY ARE SIMILAR
