Question
The circumference of a circle is 44 cm and the length of
the rectangle is 5 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 7:8, 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 × 5 = 35 cm Breadth of the rectangle = (35/7) × 8 = 40 cm Area of the rectangle = 40 × 35 = 1400 cm2
