Question

I need help, “Find the approximate side length of a square game board with an area of 105 in 2”

Answer 1

`\bf \textit{area of a square}\\\\ A=s^2~~ \begin{cases} s=sides's\\ \qquad length\\[-0.5em] \hrulefill\\ A=105 \end{cases}\implies 105=s^2\implies √(105)=s\implies 10.2469508\approx s`
