A room measures 15-1/4 inches on a blueprint with a scale of 1/4" equals 1 foot. How many feet is the room?

To determine the actual size of the room from the blueprint dimensions, it’s essential to understand the scale provided. In this case, the scale indicates that 1/4 inch on the blueprint reflects 1 foot in reality.

First, we convert the blueprint measurement from inches into a format that corresponds with the scale. The room measures 15-1/4 inches, which can be expressed as a fraction:

15-1/4 inches is the same as 15.25 inches.

Next, since the scale is 1/4" equals 1 foot, we need to figure out how many 1/4 inch segments fit into the total number of inches. This is done by dividing the total number of inches by 1/4 inch:

[

\text{Number of segments} = \frac{15.25 \text{ inches}}{0.25 \text{ inches}}

]

Calculating this gives:

[

15.25 \div 0.25 = 61

]

Since each segment represents 1 foot, the room is 61 feet in actual size. Hence, the correct choice reflects that the room measures 61 feet.
