if the ratio of similarity of the figures above is 2/3, then what is the ratio of the areas of the two figures?

Solution
For this case we can find the ratio in the following way:
10/15 = 2/3
And the ratio of the areas are given by:
[tex]\frac{A_1}{A_2}=\frac{b_1h_1}{b_2h_2}=\frac{2}{3}\cdot\frac{2}{3}=\frac{4}{9}[/tex]Then the ratio of the area is 4/9
