Maps and scale drawings are: Scale models are:   The scale that is used is a _________. For example: I cm : 200 m A map has a scale of 1 inch : 20 miles. Use the A map has a scale of 1 cm : 8 km. Use the given map distance to find the actual distance. given actual distance to find the distance on the map. 1. 2. 3. 4. two-dimensional drawings that are similar to the objects they represent. three-dimensional models that are similar to the objects they represent. ratio

5. A map has the following scale: 1 cm = 100 km 5. A map has the following scale: 1 cm = 100 km. The distance between two towns on the map is 3.2 cm. What is the actual distance between the two towns? 6. A blueprint scale is 1in : 12ft. The width of a building is 48 ft. What is the width of the building on the blueprint? 7. A model of a space shuttle has a scale of 1:52. The space shuttle has a wingspan of 78 feet. Find the model’s wingspan.
