Given
![Tiles = 100](https://img.qammunity.org/2021/formulas/mathematics/college/h4k4o1xl2wfax6cvlc47gc4owg22c97siu.png)
Required
Determine the length of one side
The given parameter represents the perimeter of the table
Since the table is a square, then
![Perimeter = 4L](https://img.qammunity.org/2021/formulas/mathematics/college/m3um67v1482214r13va22zonlm4km6ak1d.png)
Substitute 100 for Perimeter
![100 = 4L](https://img.qammunity.org/2021/formulas/mathematics/college/qn0cz6yk5ljxfaa9n585brgo7beywpc9zd.png)
Solve for L
![L= 100/4](https://img.qammunity.org/2021/formulas/mathematics/college/nx1ntet2fppoof396c8ve1wwun109cj0f2.png)
![L = 25](https://img.qammunity.org/2021/formulas/mathematics/college/ovwrlgbh79y7cax3u7lbaiedpw4wl87xp9.png)
Hence:
The length of one side is 25 tiles
