Answer 2

Step-by-step explanation:

$Let \: the \: two triangles \: be \triangle{ ABC} \: and \: \triangle{PQR }$

$We \: know \: that,$

$\frac{ ar ( \triangle ABC)}{ar(\triangle PQR)} = ( \frac{AB}{PQ})^{2}$

$\frac{ ar ( \triangle ABC)}{ar(\triangle PQR)} =( \frac{4}{9} )^{2}$

$\frac{ ar ( \triangle ABC)}{ar(\triangle PQR)} = \frac{16}{81}$
