To solve this, we can set up a proportion based on the given scale:

• The scale is 2 inches for every 30 feet.
• The actual height of the stadium is 180 feet, and we need to find the height of the scale model in inches.

We can set up the proportion as follows:

$\frac{2 \text{ inches}}{30 \text{ feet}} = \frac{x \text{ inches}}{180 \text{ feet}}$

Now, solve for $x$:

$x = \frac{2 \times 180}{30} = \frac{360}{30} = 12 \text{ inches}$

So, the height of the scale model is 12 inches.

The correct answer is B. 12 in.
