+4 a square field has an area of 479ft^2
what is the approximate length of a side of the field
give your answer to the nearest foot.
Why are you confused? What is the area of a square?
Area = S^2, where S = Side of the square.
S^2 = 479 take the square root of both sides.
S = Sqrt(479)
S = 21.89 = ~ 22 feet - side length of the field.
+23 Firstly, \(\sqrt{479}≈21.8\), making the problem mostly done already.
it will be 22 ft approximately, since the decimal point is larger than 5.
ANSWER : 22 ft
