Question: A circle and a rectangle have the same perimeter. The sides of the rectangle are 9 cm and 13 cm. What is the area of the circle?Solution:The sides of the rectangle are 9 cm and 13 cm.Perimeter of the rectangle =2(9 + 13) = 44 cmCircumference of circle = 44 cm.Here2πr = 44(22/7)r = 22r/7 = 1r = 7Area of circle = πr2 = (22/7) × 72 = (22/7) × 49 = (22 × 7)= 154 cm2
