Answer:
[tex]s\approx12.25\text{ cm}[/tex]Step-by-step explanation:
The area of a square is represented by the following expression:
[tex]\text{area}=\text{side}\cdot\text{side}[/tex]Then, if we have an area of 150 square centimeters, substitute into the formula and solve for side:
[tex]\begin{gathered} 150=s^2 \\ s=\sqrt[]{150} \\ s=5\sqrt[]{6}\approx12.25\text{ cm} \end{gathered}[/tex]
