The approximate length of a side of the field is 22ft.
What is a square ?
Square, in geometry serves as a plane figure that has four equal sides and four right (90°) angles.
To calculate the we can use the formula (LW)
But the area of square is been given as 479 ft2
Hence, 479=L^2
Then if we find the square root, we have
L=W=21.88
=22 rounded
Therefore, approximate length of a side of the field is 22ft.
