Lesson: Scale Drawings and Models Mathematics • 7th Grade
In this lesson, we will learn how to calculate the scale factor and the dimensions of both the scaled model and the actual object and apply this to real-world problems.
The distance between two cities on a map is 17 cm and the actual distance between them is 68 km. If the distance between two other cities on the same map is 15 cm, determine the real distance between them.
A line on a drawing is 3 cm long. In real life, the object represented is km long. What is the drawing scale?
James is drawing a map to a scale of . If the distance between two cities on the map is 4.5 cm, find the actual distance between them in kilometers.
