A wire in the form of a circle of radius 3.5 m is bent in the form of a rectangle, whose length and breadth are in the ratio of `6:5`. What is the area of the rectangle?A. `60cm^(2)`B. `30cm^(2)`C. `45cm^(2)`D. `15cm^(2)`

Answer» Correct Answer - B
The circumference of the circle is equal to the perimeter of the rectangule. Let l = 6x and b = 5x.
`(6x+5x)=2xx(22)/(7)xx3.5rArrx=1`
`thereforel = l = 6 cm and b = 5 cm`
`"Area of the rectangle "=6xx5=30cm^(2)`
