Answer:

Length = $18\frac{2}{5}$ feet

Step-by-step explanation:

Simplify the fraction of the width:

$12\frac{1}{2}=\frac{25}{2}$

Using the formula for Area:

$A=l*w\\l=\frac{A}{w}$

Substituting the known values:

$l=\frac{230}{\frac{25}{2}}\\l=230*\frac{2}{25}\\l=\frac{460}{25}\\l=\frac{92}{5}\\l=18\frac{2}{5}$
