Answer:

L = 882/121 feet

Step-by-step explanation:

Set the appropriate variables in the equation to the given values and solve for the unknown.

$T=2\pi\sqrt{\dfrac{L}{32}}\\\\3=2\left(\dfrac{22}{7}\right)\sqrt{\dfrac{L}{32}} \qquad\text{fill in given values}\\\\ \dfrac{3\cdot7}{44}=\sqrt{\dfrac{L}{32}} \qquad\text{multiply by $\dfrac{7}{44}$}\\\\ \left(\dfrac{21}{44}\right)^2=\dfrac{L}{32}\qquad\text{square both sides}\\\\ \dfrac{32\cdot441}{1936}=L \qquad\text{multiply by 32}\\\\ \boxed{L=\dfrac{882}{121}}\qquad\text{reduce the fraction}$
