. A square picture frame occupies an area of 112 ft2 . What is the length of each side of the picture in simplified radical form
saw5 [17]
Recall that a square is just a rectangle with all sides equal.

and the area of a rectangle is just length * width.

\bf \textit{area of a rectangle}\\\\&#10;A=length\cdot width\quad &#10;\begin{cases}&#10;length=x\\&#10;width=x\\&#10;A=112&#10;\end{cases}\implies 112=x\cdot x\implies 112=x^2&#10;\\\\\\&#10;\sqrt{112}=x\implies \sqrt{16\cdot 7}=x\implies \sqrt{4^2\cdot 7}=x\implies 4\sqrt{7}=x
