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?
millimeters
To find the length of the building in the drawing, we can set up a proportion:
3 millimeters = 2 meters
Let x be the length of the building in the drawing.
So, we have the equation:
3 millimeters/2 meters = x millimeters/206 meters
Solving for x by cross-multiplying, we get:
2 * x = 3 * 206
2x = 618
Dividing both sides by 2, we get:
x = 309
Therefore, the length of the building in the drawing is 309 millimeters.
