Question
The circumference of a circle is 110 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 7:6, respectively.Solution
Let the radius of the circle = ‘r’ cm Circumference of the circle = 2πr 110 = 2 × (22/7) × r r = 17.5 Radius of the circle = 17.5 cm Length of the rectangle = 17.5 × 4 = 70 cm Breadth of the rectangle = (70/7) × 6 = 60 cm Area of the rectangle = 60 × 70 = 4200 cm2
