We know that the formula for the area of a square is:
[tex]A=S^2[/tex]Where S is the lenght of one of the sides.
Since we know the area of the square picture frame, we can use this formula and find the lenght of one side as following:
[tex]\begin{gathered} S^2=55\rightarrow S=\sqrt[]{55} \\ \\ \Rightarrow S=7.41 \end{gathered}[/tex]Therefore, the correct answers are:
A) 7 inches
B) 7.4 inches
