Answer:

1.3 km by 1.3 km

Step-by-step explanation:

The area of a square is given by

A = s^2 where s is the side length

1.69 km^2 = s^2

Take the square root of each side

sqrt(1.69 km^2) = sqrt(s^2)

1.3 km = s

Answer: A≈2.86

Step-by-step explanation:  multiply the area value by 144

A=a2=1.692≈2.8561
