actual length of the east side.
2 in.

Explanation:

Step1: Simplify the scale ratio

The scale is \(6\) in. : \(30\) yd. Simplify \(\frac{6}{30}=\frac{1}{5}\). So the scale is \(1\) in. : \(5\) yd.

Step2: Find the multiplier

From the scale \(1\) in. : \(5\) yd, the number you multiply the length in the scale drawing by to get the actual length is \(5\).

Step3: Calculate the actual length

If the length in the scale drawing is \(2\) in., then the actual length \(L = 2\times5=10\) yd.

Answer:

The number to multiply by is \(5\), and the actual length of the east - side is \(10\) yd.
