A building has a height of 125 meters and a length of 80 meters. On a scale drawing of the building, the height is 25 cm.

What is the length of the building on the scale drawing?

The length of the building on the scale drawing is

We can solve this problem by setting up a proportion based on the given information.

The actual height of the building is 125 meters, and the height on the scale drawing is 25 cm. The ratio of the scale drawing to the actual building is:

\[
\frac{\text{Height on drawing}}{\text{Actual height}} = \frac{25 \, \text{cm}}{125 \, \text{m}} = \frac{25 \, \text{cm}}{12500 \, \text{cm}} = \frac{1}{500}
\]

This tells us that every 1 cm on the drawing represents 500 cm in real life.

Now, we can use the same scale to find the length of the building on the scale drawing. The actual length of the building is 80 meters, which is 8000 cm.

Using the scale ratio:

\[
\frac{1}{500} = \frac{\text{Length on drawing}}{8000 \, \text{cm}}
\]

Solving for the length on the drawing:

\[
\text{Length on drawing} = \frac{8000}{500} = 16 \, \text{cm}
\]

Thus, the length of the building on the scale drawing is **16 cm**.
