## Geometry: Common Core (15th Edition)

24 $in^{2}$
The ratio of the areas is the square of the ratio of corresponding sides $\frac{3^{2}}{6^{2}}$=$\frac{9}{36}$ Set up a proportion using the ratio of the areas found above: $\frac{9}{36}$=$\frac{6}{A}$ Cross multiply 9A=6(36) 9A=216 Divide both sides by 9 A=24
