Explanation:

Step1: Set up the proportion

Let \(x\) be the actual length of the airplane. The ratio of model length to actual length is the same for both the wingspan and the length. So, \(\frac{12}{x}=\frac{17}{1224}\)

Step2: Cross - multiply

Cross - multiplying gives \(17x = 12\times1224\)

Step3: Solve for \(x\)

First, calculate \(12\times1224 = 14688\). Then \(x=\frac{14688}{17}\)
\(x = 864\)

Answer:

The actual length of the airplane is \(864\) feet.
