Answer:
The correct answer option is 37.5 feet.

Given the above information, we are to find the actual height of the building.
To find this, we will use the ratio method.
![\frac {1 inch} {30feet} = \frac {1.25 inch} {x}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fdn6y4kmbp5ts07kk8f03ls7tt9rker9q4.png)
![x = 37.5](https://img.qammunity.org/2020/formulas/mathematics/middle-school/13qcyegt5g91seuf4fh8mrva26ha4m7u2x.png)
Therefore, the actual height of the building shown is 37.5 feet.
