SUMMARY
The minimum length of a plane mirror required for a person to view a 5m drawing is 2.5m. This conclusion is based on the principle that a plane mirror reflects an image that appears at the same distance behind the mirror as the object is in front of it. Therefore, to see the entire height of the 5m drawing, the mirror must be at least half the height of the drawing, which is 2.5m. This ensures that the viewer can see the full image without any obstruction.
