Answer:
2 millimeters
Step-by-step explanation:
Ethan used the scale 1 millimeter : 5 meters.
This means that 1 millimeter in the drawing represents 5 meters in actual life.
The actual length of the garage is 10 meters. Therefore:
5 meters = 1 millimeter
=> 10 meters = (10 * 1) / 5 = 2 millimeters
The garage is 2 millimeters long in the drawing.
