Explanation:

Step1: Identify the scale factor

The scale is \(1\) in. : \(10\) ft, which means each inch in the drawing represents \(10\) feet in actual.

Step2: Multiply the scale - drawing length of the north side by the scale factor

The length of the north side in the scale drawing is \(9\) in.
The actual length \(L\) is given by the formula \(L=\text{scale - drawing length}\times\text{scale factor}\)
So, \(L = 9\times10\)

Answer:

\(90\)
