slega [8]

Answer:

0.8 meters

Step-by-step explanation:

We know that One Shell Square is the tallest building in New Orleans with a height of about 212 meters and Marlie is creating a scale model of this building, using the scale 250 meters : 1 meter.

So to find the height of the scale model, we can simply use the ratio method.

$\frac{212 m}{250m} =\frac{x}{1}$

$x=\frac{212}{250}$ = $0.848$

Therefore, the height of the scale model to the nearest tenth of a meter will be 0.8 meters.
