(A) The area of the square field is $6050\, m^2$. Let the side of the square be $a$. Then $a^2 = 6050$.The diagonal of a square is given by $d = a\sqrt{2}$.Thus,$d^2 = 2a^2 = 2 	imes 6050 = 12100\, m^2$.Therefore,the length of the diagonal $d = \sqrt{12100} = 110\, m$.The speed is given as $10\, m$ per $30$ seconds,which is $10\, m$ per $0.5$ minutes.Time taken = $\frac{	ext{Distance}}{	ext{Speed}} = \frac{110\, m}{10\, m / 0.5\, 	ext{min}} = 11 	imes 0.5 = 5.5$ minutes.This is equal to $5 \frac{1}{2}$ minutes.

The area of a square field is $6050\, m^2$. How much time will it take to reach from one of its corners to the opposite corner at the rate of $10\, m$ in every $30$ seconds?
