Planning & EstimatingQuestion 633 of 700
On a drawing at 1/4 inch = 1 foot-0 inches, a wall measures 3 inches long on the paper. What is the actual length of that wall?
a.3 feet
b.12 feet
c.48 feet
d.9 feet
Explanation
At 1/4 inch = 1 foot, each inch on the paper equals 4 feet (because 1 divided by 1/4 = 4). So 3 inches x 4 feet per inch = 12 feet. Correct answer is 12 feet. '3 feet' wrongly treats one inch as one foot. '48 feet' uses 16 feet per inch. '9 feet' has no valid basis.
