Answer:

Area of the square is 12.5 square meter

Step-by-step explanation:

Speed of the personv=6km /hr=6 \times\frac{1000}{3600} =10/6 m/s

Time taken to complete the diagonal is t=3

Length of the diagonal is \frac{10}{6} \times 3=5m

Sides of the square be x m

from Pythagoras theorem

Diagonal ^2=x^2+x^2\\5^2=2x^2\\x^2=\frac{25}{2} \\x^2=12.5 m^2\\

Area of the square is 12.5 square meter
