Question

Jackson measured a swimming pool and made a scale drawing. The pool, which is 30 meters long in real life, is 15 millimeters long in the drawing. What scale did Jackson use?

Answer 1

Jackson used a scale factor of 1:2000 for his scale drawing of the swimming pool, meaning 1 millimeter on the drawing represents 2 meters of the actual pool.

Step-by-step explanation:

Jackson used a scale to create a scale drawing of a swimming pool. The real-life swimming pool is 30 meters long, and on his drawing, it measures 15 millimeters. To find the scale factor Jackson used, we divide the actual length by the drawing length.

Scale factor calculation:
Actual length / Drawing length = 30 meters / 15 millimeters

First, convert the actual length to millimeters because the drawing length is given in millimeters. Since 1 meter = 1000 millimeters, 30 meters is 30000 millimeters.

Now, calculate the scale factor:
30000 millimeters / 15 millimeters = 2000

So, the scale factor Jackson used is 1:2000, which means 1 millimeter on the drawing represents 2000 millimeters or 2 meters in real life.
