Answer:
The perimeter of squire is 32 cm
Then side of square = 32/4
=8 cm
Then area of square =8x8
=64 cm ²
The ratio of the area of a rectangle to that of a square is 3:2
then area of rectangle = 3/2 ×64=96 cm ²
Let the length of rectangle angle is 3x, and breadth is 2x
Then area of rectangle =3x×2x=96
⇒6x²=96⇒x² =16⇒x=4 cm
Then length of rectangle =3×4=12 and breadth =2×4=8 cm
Then perimeter of rectangle =2(12+8)=40
Then difference between the perimeter of the square and the rectangle =40−32=8 cm
