Answer

$\frac{9}{4}$

Work Step by Step

The ratio of the areas of two similar triangles equals the square of the ratio of the lengths of any two corresponding sides; that is, $\frac{A1}{A2}$ = $(\frac{a1}{a2})^{2}$ Given that the ratio of the length of the corresponding sides = $\frac{s1}{s2}$ = $\frac{3}{2}$ The ratio of $\frac{A1}{A2}$ = $(\frac{a1}{a2})^{2}$ = $(\frac{3}{2})^{2}$ = $\frac{9}{4}$
