Answer:
[tex]\sqrt {55}[/tex] inches
Step-by-step explanation:
Let x inches be the length of one side of the frame. The frame is the square, so all sides have the same lengths.
Use formula [tex]A=x^2\ in^2[/tex] connecting the area of the square and the side length of the square.
Since the area ofthe square is 55 square inches, we have
[tex]x^2 =55\\ \\x=\sqrt {55}\ in[/tex]
