Question
The radius of a circle is derived from its
circumference, which measures 88 meters. A rectangle features a length that exceeds the circle’s radius by 50%. Additionally, the rectangle's breadth is two-thirds of its length. Calculate the perimeter of this rectangle. (Use 'π' = 22/7)Solution
Circumference of circle = 2 X π X radius So, 2 X (22/7) X radius = 88 Or, radius = 88 X (7/44) Or, radius = 14 m Length of rectangle = 1.5 X 14 = 21 m Breadth of rectangle = (2/3) X 21 = 14 m Perimeter of rectangle = 2 X (21 + 14) = 70 m
