In reading a blueprint where the scale is 3"=1 ft, 4-1/2" on the blueprint would equal what actual size?

Explanation:
Converting blueprint measurements using the given scale: 3 inches on the drawing represent 1 foot in real size. That means each inch on the plan equals one-third of a foot. So, 4.5 inches × (1/3) foot per inch = 1.5 feet. To put that in inches, 1.5 feet × 12 inches per foot = 18 inches. Therefore, 4-1/2 inches on the blueprint equals 18 inches in actual size.
