The length of the actual wall is 8.75 ft.
To calculate this, you first convert the scale to real-life dimensions by multiplying the length on the blueprint (3 in) by the scale factor (30).
3 in x 30 = 90 in
Next, convert the length from inches to feet by dividing by 12:
90 in รท 12 = 7.5 ft
Therefore, the length of the actual wall is 7.5 ft.
