It depends completely on the object. The mirror has to be of at least half the height of the object. Otherwise there will be no image of the object on the mirror.
The size of the mirror needs to be at least half the height of the person standing in front of it in order for the person to see their full length image. Therefore, a 3 ft tall vertical plane mirror would be the smallest size in which a 6 ft tall person can see their full length image.
To see the full length of an object using a plane mirror, the mirror should be at least half the height of the object. This allows the top half of the object to be reflected in the mirror, giving the illusion of seeing the full length of the object.
A mirror should be at least half the height of the person using it to see a full vertical image. This allows the person to see themselves from head to toe without any obstruction in the mirror.
The minimum length of the mirror needed for the tall man to see his full image would be 6 feet. This is because the mirror needs to be at least the same height as the person in order to capture their full image.
The least possible quantity is zero.

Install them so that they are off vertical by at least one diameter over the length of the run.
100mm

Not possible, you need at least the length of two sides and the included angle.
No. Or at least, I think not.
5.5 inches
0.000...1cm length on two sides. 19.999...9cm length on the other two.
I don't think it is possible. You would have to know at least one other measurement such as the angle between the length and width or the length of one of the sides.
When a mirror is used in lieu of an observer when towing skiers, the mirror must have at least 78 square inches of viewing area and have a field of vision of at least 170 degrees mounted on the vessel.
