Answer: Ratio of perimeter of square and rectangle is 4:5
Given : Ratio of area of square and rectangle is 2:3
& side length of square is equal to breadth of rectangle
To find : Ratio of perimeter of square and rectangle
Step wise solution: Let the side length of square is x
i.e breadth of rectangle is also x
let length of rectangle is y
hence, area of square is x²
area of rectangle is xy
given =
i.e =
i.e y=1.5x
now, perimeter of square is 4x
perimeter of rectangle is 2(x+y)
= 2*2.5x
=5x
now ratio of perimeter of square and rectangle is = 4:5
Hence, ratio of perimeter of square and rectangle is 4:5
