A circular wire of diameter $42 cm$ is bent in the form of a rectangle whose sides are in the ratio $6 : 5$. The area of the rectangle is $\displaystyle \left ( \pi =\frac{22}{7} \right )$

The wire is bent into a rectangle, so the circumference of 42 pi becomes the perimeter of the rectangle, and using pi equals 22/7 gives 132 cm. If the sides are 6x and 5x, the perimeter is 22x, making x equal to 6 and the sides 36 cm and 30 cm. Multiplying 36 by 30 gives the area as 1080 cm squared.
