So,
We can refer to the formula for the area of a rectangle.
A = l*w
Since we are solving for the length, it would be easier for us if we divided both sides of the equation by w.
\(\frac{A}{w} = l\)
Now we can plug in the values to get the answer.
\(\frac{118.08}{9.6} = l\)
\(\frac{11808}{960} = l\)
\(12.3 = l\)
The length of the park is 12.3 km.
