(C) Let the side of the square be $a \, cm$.Given that the radius of the circle is equal to the side of the square,so radius $r = a$.The circumference of the circle is $2 \pi r = 132 \, cm$.Using $\pi = 22/7$,we have $2 	imes (22/7) 	imes a = 132$.$a = (132 	imes 7) / (2 	imes 22) = 66 	imes 7 / 22 = 3 	imes 7 = 21 \, cm$.The length of the rectangle is $3/5$ of the side of the square,so length $l = (3/5) 	imes 21 = 63/5 = 12.6 \, cm$.The breadth of the rectangle is given as $b = 8 \, cm$.The area of the rectangle is $l 	imes b = 12.6 	imes 8 = 100.8 \, cm^2$.

The length of a rectangle is $3/5$ of the side of a square. The radius of a circle is equal to the side of the square. The circumference of the circle is $132 \, cm$. What is the area of the rectangle if the breadth of the rectangle is $8 \, cm$? (in $cm^2$)
