Circumference of circle = Perimeter of rectangle ( since it is bent from the circle)
Circumference = 2πr
=2 × 22/7 × 42
= 264cm
Now we are given The sides are in ratio of 6:2
Let them be 6x and 2x
so 2(6x + 2x ) = 264
2 × 8x = 264
8x = 264/2
8x = 132
x = 16.5
2x = 16.5 × 2
= 33cm
The correct answer should be 33
