Answer:
16 feet
Explanation:
The area of a square can be found using the following formula.
![A=s^2](https://img.qammunity.org/2021/formulas/mathematics/high-school/o9zxg41yvoa3srjrnclaalypba9y5e71gu.png)
We know that the area of the playground is 263 ft^2. Therefore,
A=263 ft^2
![263 ft^2= s^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/2r1tm1xc9w9d0ydxduuag5wpr186y4ye8w.png)
We want to find out what s, the side length, is. s is being squared. The inverse of a square is a square root. Therefore, we must take the square root of both sides.
![√(263 ft^2) =√(s^2)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/6xk87ymdkcqbx5h8h4dvsog74su89m2a3o.png)
![√(263ft^2)=s](https://img.qammunity.org/2021/formulas/mathematics/middle-school/q0y4acce1k46ito9ykebb7rec8mxa9q5ou.png)

Round to the nearest foot. The 2 in the tenth place tells us to leave 16 as is.

The approximate length of each side of the playground is 16 feet.
