Scale Drawings

Scale Drawings An enlargement or reduction drawing of an actual object or place.

Scale Drawings An enlargement or reduction drawing of an actual object or place. Similar to the actual (proportional)

Scale Drawings An enlargement or reduction drawing of an actual object or place. Similar to the actual (proportional) Scale: ratio of distance on the drawing to the actual distance

Example 4 A map has a scale of 1 in = 25 mi. The distance between two cities on the map is 4 ½ in. What is the actual distance?
