Question

Being timed, help asap!! The figures are similar. Give the ratio of the area/perimeter of the first figure to the second figure

Answer 1

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.

$(\frac{9}{5})^2=\frac{81}{25}$
