Answer:
5 feet
Step-by-step explanation:
Since you know that the ratio is 1:250, you set up a second ratio that looks like this:
x:1,250, where x is the unknown height of the model.
Then divide 1,250 by 250 bc the real building is 250 times larger than the model. 1,250/250=5, so the model should be 5 feet tall
