Juno calculated the area of a square to be 4/9 square yard. Which shows the side length of the square?
A 2/9 yard
B 4/9 yard
C 2/3 yard
D 8/9 yard

Respuesta :

[tex]\bf \textit{area of a square}\\\\ A=s^2~~ \begin{cases} s=side's~length\\ --------\\ A=\frac{4}{9} \end{cases}\implies \cfrac{4}{9}=s^2 \\\\\\ \sqrt{\cfrac{4}{9}}=s\implies \cfrac{\sqrt{4}}{\sqrt{9}}=s\implies \cfrac{2}{3}=s[/tex]
