Diagonal scale
The document describes constructing a diagonal scale with a representative fraction (RF) of 1/500 to measure distances in meters and decimeters up to a maximum of 80 meters. It provides instructions to make a scale 16 cm long based on the given RF and maximum measurement. An example is then given to measure a distance of 47.8 meters using the new scale.
