Question

coach hernandez made a scale drawing
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?
ft

Explanation:

Step1: Find the scale factor

The west side of the scale drawing is \(5\) inches and the actual west - side is \(50\) feet. The scale factor \(k\) is found by dividing the actual length by the scale - drawing length. So \(k=\frac{50}{5} = 10\) (i.e., \(1\) inch in the scale drawing represents \(10\) feet in actual).

Step2: Calculate the actual north - side length

The north - side of the scale drawing is \(9\) inches. Using the scale factor \(k = 10\), the actual length \(L\) of the north - side is \(L=9\times k\). Substitute \(k = 10\) into the formula: \(L=9\times10\).

Answer:

\(90\)
