Asquare field has an area of 479 ft2. what is the approximate length of the field

To determine the approximate length of the square field simply take the square root of the square area.

A = s^2 = 479 ft ^2

s^2 = 479
s = sq root of 479
s = 21.88 ft or approximately 21.9 or 22 ft.

The approximate length of the field is 22 feet.
