Let’s convert the distance between points into one unit of measurement:
AB = 2.1 dm = 21 cm,
BC = 9 cm = 9 cm,
AC = 120mm = 12cm.
The distance between the extreme points should be the maximum suggested. This is 21 cm, which means the extreme points A and B. It follows that in the middle there is point C.
