Answer 1

Answer: 36 cm

Step-by-step explanation:

Since, $\triangle ABC\sim \triangle XYZ$

In the similar triangles the corresponding sides are in the same proportion,

$\implies \frac{AB}{BC} = \frac{XY}{YZ}$

$\implies \frac{6}{18} = \frac{12}{YZ}$

$\implies 6YZ =18\times 12$

$\implies 6YZ =216$

$\implies YZ=36\text{ cm}$
