Question
The circumference of a circle is 44 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 2:1, respectively.Solution
Let the radius of the circle = ‘r’ cm Circumference of the circle = 2πr 44 = 2 × (22/7) × r r = 7 Radius of the circle = 7 cm Length of the rectangle = 7 × 4 = 28 cm Breadth of the rectangle = (28/2) × 1 = 14 cm Area of the rectangle = 14 × 28 = 392 cm2
