This is just a porportion. So if 250 meters is 1 meter than: 250/1

And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x

Set them equal to each other 250/1=212/x

Cross multiply: 212=250x

Divide to find x: 212/250=x
x=212/250
x=0.848

So the height of the model, to the nearest 10th would be 0.8 meters.
