Answer:
Step-by-step explanation:
Ratios of perimeters is a one-to-one measure. From the figure on the left to the one on the right the ratio of the one-to-one measure is 45/25 which reduces to 9/5.
Area is a squared measure. Once we have the perimeter reduced (we do), we square those perimeter measures to find the area ratio.
[tex](\frac{9}{5})^2=\frac{81}{25}[/tex]
