Question

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

Answer 1

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.
