Let bredth of rctngle=b
then length = 9b.
area=l*b =9b * b = 9 b^{2}
then perimeter = 2(9b + b)=20b

if it area of square then side of square is= a^{2} =9 b^{2}

a=side=3b
then its perimeter = 4.3b = 12b

ratio of perimeter=

rectangle : square
         20b:12b
           10:6
             5:3

hence ratio is 5:3
