Lacey measured a community college and made a scale drawing. She used the scale 3 millimeters : 2 meters. A building at the college is 206 meters long in real life. How long is the building in the drawing?

Answer 1

To find the length of the building in the drawing, we can set up a proportion using the given scale:

3 millimeters / 2 meters = x millimeters / 206 meters

Cross multiplying, we get:

2 meters * x millimeters = 3 millimeters * 206 meters

2x = 618

Dividing both sides by 2, we find:

x = 309 millimeters

Therefore, the length of the building in the drawing is 309 millimeters.
