A building has a length of 40 m. The length of its scale model is 25 cm. What scale factor was used to make the scale model?
Marizza181 [45]
The answer is 1 cm = 1.6m. We know this because the scale model was 25 cm and the building was 40m. To simplify, our proportion is 40 meters /25 centimeters to x meters/1 centimeter. 40/25= 1.6, so we can say that x (the scale factor) is 1 cm to 1.6 m.
