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?
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.
