Question
The length of a rectangle, area of which is 252
cm2, is equal to the radius of a circle of area 2464 cm2. Find the perimeter of the rectangle?Solution
Let the radius of the circle = r Area of circle = 2464 = 22/7 × r × r ⇒ r = 28 cm Area of rectangle = 252 = L × B = 28 × B ⇒ B = 9 cm Perimeter = 2 × (L + B) = 2 × (28 + 9) = 74 cm Â
