Since the shape of the polygon is a square, all 4 sides have the exact same length. This means that Perimeter = 4 * length of one side, or;
![P = 4 s\\ 20=4s\\ s=\frac{20}{4}=5](https://tex.z-dn.net/?f=%20P%20%3D%204%20s%5C%5C%2020%3D4s%5C%5C%20s%3D%5Cfrac%7B20%7D%7B4%7D%3D5)
Thus, the length(value) of S is
5.
Answer:
can't see the answers but I think it's 2.5
The pattern is in threes so all you have to do is simply add 3 to 21 and so on and so on
116/240 which simplifies to 29/60 by dividing 116/240 by 4/4.
