Question

coach hernández made a scale drawing of the school gym. the scale of the drawing is 1 in. : 10 ft. find the actual length of the north side of the gym. what number can you multiply each length in the scale drawing by to find the actual length? what is the actual length of the north side of the gym?

Explanation:

Step1: Analyze the scale

The scale is \(1\) in. : \(10\) ft. This means \(1\) inch on the drawing represents \(10\) feet in actual.

Step2: Find the actual length

The north - side in the scale drawing is \(9\) inches. Multiply the scale - drawing length by the scale factor.
The formula for actual length \(L\) is \(L=\text{scale - drawing length}\times\text{scale factor}\).
Substitute the values: \(L = 9\times10\)

Answer:

\(90\)
