Answer:
13 feet
Explanation:
The scale factor is given as one-fourth inch to one foot. This means that 1 inch on the blueprint represents 4 feet in actuality.
If the wall on the blueprint is 3.25 inches long, we can use the scale factor to find the actual length of the wall:
Actual length = Blueprint length × Scale factor
Actual length = 3.25 inches × 4 feet/inch
Actual length = 13 feet
So, the actual length of the wall is 13 feet.
