Lesson 14. Unit 4. Grade 7 EngageNY


This Instructional Activity is a part of the Lesson 14, Unit 4, Grade 7. Recall the definition of the scale factor of a scale drawing. The scale factor is the quotient of any length of the scale drawing and the corresponding length of the actual drawing. Since the scale factor is not given, how can the given diagrams be used to determine the scale factor? We can use the gridlines on the coordinate plane to determine the lengths of the corresponding sides and then use these lengths to calculate the scale factor.
