To find the width of the model, we'll first determine the length of the classroom by dividing the given length of the model (42 in) by the given ratio of the length to the width (2.4).

Length of classroom = Length of model / Ratio of length to width
Length of classroom = 42 in / 2.4
Length of classroom = 17.5 in

Since the length of the classroom is 2.4 times the width, we can find the width by dividing the length by 2.4.

Width of classroom = Length of classroom / 2.4
Width of classroom = 17.5 in / 2.4
Width of classroom ≈ 7.29 in

Therefore, the width of the model should be approximately 7.29 inches.
