first find the ratio of their radii
so πR×R//πr×r=9/4
R.R/r.r=9/4
R/r=3/2
so ratio of radii is 3/2
now perimeter=2πr
2πR/2πr
3/2 will be the ratio of perimeters when 2π will be cancelled
so πR×R//πr×r=9/4
R.R/r.r=9/4
R/r=3/2
so ratio of radii is 3/2
now perimeter=2πr
2πR/2πr
3/2 will be the ratio of perimeters when 2π will be cancelled
