Question

Find the ratio of the perimeters for each pair of similar figures.
1. 2 regular pentagons with areas 50 inches squared and 162 inches squared.
2. 2 circles with areas 27π inches squared and 48π inches squared.
1. P1/P2 = sqrt(A1/A2)
P1/P2 = sqrt(50/162) = 0.56

2. C1/C2 = sqrt(A1/A2)
C1/C2 = sqrt(27pi/48pi) = 0.75
C = Circumference.
