The area of the circle is 616 cm 2. What is the area of the rectangle?

given :- Area of the circle = 616
⇒ πr² = 616
Put the value of π = 22/7 in above equation.
we will get,
⇒ r² = 196
⇒ r = 14 cm
Length of the rectangle = Diameter of the circle = 2r
Breadth of the rectangle = Radius of the circle = r
∴ Area of the rectangle = Length x Breadth
∴ Area of the rectangle = 28 × 14 = 392 cm²
