Four circles of equal radii are described about the four corners of a square so that each touches two of the other circles. If each side of the square is 140 cm and then area of the space enclosed between the circumference of the circle is

4200 cm²

2100 cm²

7000 cm²

7200 cm²

4200 cm²

Radius of ecah circle =

Area of the four sectors =

Area of square = (side)² = (140)² = 19600 cm²
∴ Area of enclosed space = (19600 - 15400) cm²
= 4200 cm²
