# A square field has an area of 479 ft^{2}.What is the approximate length of a side of the field?

**Solution:**

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

Area of a square = side × side

Area of a square = side^{2} square units

Area of a square field = 479 ft^{2} [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.

## A square field has an area of 479 ft^{2}.What is the approximate length of a side of the field?

**Summary:**

A square field has an area of 479 ft^{2}. The approximate length of a side of the field is 21.9 feet.
