#### Answer

The ratio of the perimeters 4:3
The ratio of the areas 16:9

#### Work Step by Step

Find the corresponding side ratio.
$\frac{8}{6}$=$\frac{4}{3}$
The ratio of the perimeters is equal to the ratio of the corresponding sides.
$\frac{4}{3}$=$\frac{4}{3}$.
The ratio of the areas is equal to the square of the ratio of corresponding sides.
$\frac{4^{2}}{3^{2}}$=$\frac{16}{9}$.
