Let's say the width of the rectangular classroom is represented by "w". Since the length is 2.4 times the width, the length would be 2.4w.
We're given that the length of the model is 42 inches, which represents 2.4w.
So, 2.4w = 42.
To solve for w, divide both sides of the equation by 2.4:
w = 42 / 2.4 = 17.5 inches.
Therefore, the width of the model should be 17.5 inches.
