Correct Answer: 7546 m 2
Solution : Given: The perimeter of the square = 196 m Perimeter of a square = 4 $×$ side ⇒ 196 = 4 × side ⇒ side = $\frac{196}{4}$ = 49 m Now, Area of the circle = $\pi ×$ radius 2 ⇒ Area of the circle = $\pi ×$ (49) 2 ⇒ Area of the circle = 2401 $× \frac{22}{7}$ = 7546 m 2 Hence, the correct answer is 7546 cm 2 .
