Question

Sofia drew a scale drawing of a community college. In real life, a building at the college is 129 meters long. It is 43 centimeters long in the drawing. What scale did Sofia use for the drawing?

Answer 1

To determine the scale Sofia used for her drawing, we need to find the ratio between the length in the drawing and the actual length. The scale Sofia used for the drawing is 1 centimeter = 3 meters.

Step-by-step explanation:

To determine the scale Sofia used for her drawing, we need to find the ratio between the length in the drawing and the actual length. The length of the building in the drawing is 43 centimeters and the actual length is 129 meters. We can set up a proportion:

43 centimeters / 129 meters = x centimeters / 1 meter

By cross multiplying and solving for x, we find that the length in the drawing represents 43 centimeters / 129 meters = 1/3 of a centimeter in real life. Therefore, the scale Sofia used for the drawing is 1 centimeter = 3 meters.
