Question
The circumference of a circle is 33 cm and the length of
the rectangle is 8 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 3:2, respectively.Solution
Let the radius of the circle = ‘r’ cm Circumference of the circle = 2πr 33 = 2 × (22/7) × r r = 5.25 Radius of the circle = 5.25 cm Length of the rectangle = 5.25 × 8 = 42 cm Breadth of the rectangle = (42/3) × 2 = 28 cm Area of the rectangle = 28 × 42 = 1176 cm2
