Let the radius of the circle be r cm. So, the length of the rectangle = 1.25r cm and the breadth of the rectangle = 0.90r cm Given that, ⇒ πr2 – 1.25r × 0.90r = 290.16 ⇒ 3.14r2 – 1.125r2 = 290.16 ⇒ r2 = 290.16/2.015 ⇒ r2 = 144 ⇒ r = 12 Length = 1.25 × 12 = 15 cm Breadth = 0.90 × 12 = 10.8 cm Perimeter of rectangle = 2(15 + 10.8) = 51.6 cm
