The correct answer is 7.5 ft.
To find the actual length of the wall, you would take the length of the wall in the blueprint (3 in) and multiply it by the scale (30).
3 in * 30 = 90 in
To convert 90 inches to feet, you would divide by 12 (since there are 12 inches in a foot).
90 in / 12 = 7.5 ft
Therefore, the length of the actual wall is 7.5 ft.
