Option 3 : 560

Given:

Length of the rectangle = (2/5) × Radius of the circle

Area of the square = 4900 m2

The breadth of the rectangle = 20 m

Formula used:

Area of a square = (Side)2

Area of a rectangle = Length × Breadth

Calculation:

Side of the square = √4900 = 70 m

The radius of the circle = 70 m

Length of the rectangle = (2/5) × 70 = 28 m

Area of the rectangle = 28 × 20 = 560 m2

∴ The area of the rectangle is 560 m2.
