To find the length of the actual wall, we need to use the scale ratio.
The ratio 1 : 35 means that 1 inch in the blueprint corresponds to 35 inches in real life.
Therefore, to find the length of the actual wall, we need to multiply the length of the wall in the blueprint (3 inches) by the scale ratio (35).
3 inches * 35 = 105 inches.
To convert inches to feet, we divide by 12 (since there are 12 inches in a foot).
105 inches / 12 = 8.75 feet.
Therefore, the length of the actual wall is 8.75 feet.
Choice: 8.75 feet
