Asquare playing field has an area of 1255 square yards. about how long is each side of the field? explain how to do this problem

  about 35.4 yards

Step-by-step explanation:

Make use of the formula for the area of a square and solve for the side length. The area (A) of a square of side length s is given by ...

  A = s²

You are given A and asked to find s. So you have

  1255 yd² = s²

To find s, you take the square root of both sides of the equation.

  √(1255 yd²) = √(s²)

  35.426 yd ≈ s . . . . . the square root of 1255 is irrational, so we have shown an approximation rounded to 3 decimal places.

Each side of the field is about 35.4 yards long.
