C 36 inches
To find the length in the drawing, we can convert the actual length of the rotors to inches using the given scale.
12 feet = 12 feet x 12 inches/1 foot = 144 inches
Since 1 inch in the drawing represents 4 feet in real life, we can set up the proportion:
1 inch in drawing / 4 feet in real life = x inches in drawing / 144 inches in real life
Cross multiplying:
4x = 144
x = 36
Therefore, the rotors are 36 inches long in Julie's drawing.
