6. A
field has an area of 479 ft². What is the approximate length of a side of the field?
Give your answer to the nearest foot. Explain your response.

Answer 1

Explanation:

The number of square units required to fill a square is the area.

Area of a square = side × side

Area of a square = side2 square units

Area of a square field = 479 ft2 [Given]

So the side can be determined by:

Length of a side of the field = √479 = 21.9 feet

Therefore, the length of a side of the field is 21.9 feet.
