Question
The circumference of a circle is 22 cm and the length of
the rectangle is 4 times the radius of the circle. Find the area (in cm2) of the rectangle, if the ratio of length and the breadth of the rectangle is 7:11, respectively.Solution
Let the radius of the circle = ‘r’ cm Circumference of the circle = 2πr 22 = 2 × (22/7) × r r = 3.5 Radius of the circle = 3.5 cm Length of the rectangle = 3.5 × 4 = 14 cm Breadth of the rectangle = (14/7) × 11 = 22 cm Area of the rectangle = 22 × 14 = 308 cm2
