To find the length of the actual wall, we need to use the given scale of the blueprint, which is 1 inch on the blueprint equals 35 inches in reality.
Since the wall on the blueprint is 3 inches, we calculate the actual length of the wall in inches by multiplying the length on the blueprint by the scale factor:
3 inches (blueprint) * 35 (scale factor) = 105 inches (actual size)
Now we need to convert inches to feet, knowing that 1 foot equals 12 inches:
105 inches รท 12 inches/foot = 8.75 feet
Therefore, the length of the actual wall is 8.75 feet.
