Solution:
Given:
From the question, the tent can be sketched as shown below;
Since the zipper acts as a perpendicular bisector to the base of the tent, the base is split into two equal parts.
From the sketch, a right triangle can be drawn out to get the side of the tent.
Using Pythagoras theorem to get the side of the tent,

Hence,
![\begin{gathered} \text{hypotenuse}^2=opposite^2+adjacent^2 \\ x^2=5^2+12^2 \\ x^2=25+144 \\ x^2=169 \\ \text{Taking the square root of both sides,} \\ x=\sqrt[]{169} \\ x=13\text{feet} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/2ee30c3zx889zs0pzqedtxw97ufcu1lsci.png)
Therefore, the distance of the side of the tent is 13 feet.
