To find the height of the scale model of the Eiffel Tower, we can use the scale factor of 1:750. This means that every 750 meters on the real Eiffel Tower corresponds to 1 meter on the model.
The formula to determine the height of the scale model is:
\[ \text{Height of model} = \frac{\text{Height of Eiffel Tower}}{\text{Scale factor}} \]
Given that the height of the Eiffel Tower is 301 meters, we can plug in the values:
\[ \text{Height of model} = \frac{301 \text{ meters}}{750} \]
Calculating this:
\[ \text{Height of model} \approx 0.4013333 \text{ meters} \]
Rounding to the nearest tenth of a meter:
\[ \text{Height of model} \approx 0.4 \text{ meters} \]
Therefore, the height of the scale model is:
\[ \boxed{0.4} \text{ m} \]
