In this case, we'll have to carry out several steps to find the solution.
Step 01:
Fabric (square)
area = 9 / 36 ft²
length = ?
Step 02:
square area = s²
[tex]\begin{gathered} \frac{9}{36}=s^2 \\ \sqrt[]{\frac{9}{36}}\text{ = s} \\ \frac{3}{6}\text{ = s} \\ \frac{1}{2}\text{ = s} \end{gathered}[/tex]The answer is:
The length of each side is 1/2 ft
