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 \frac{x^{2} }{xy}= \frac{2}{3}

i.e \frac{x}{y}= \frac{2}{3}

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 \frac{4x}{5x} = 4:5

Hence, ratio of perimeter of square and rectangle is 4:5
