The height of a tower is shown as 25 mm in a drawing. The actual height is 20 m . What is the scale of the drawing? 1:250 1:800 $$ 1: 500 $$ $$ 1: 400 $$

Question

To find the scale of the drawing, we need to compare the height shown in the drawing to the actual height.

1. The height in the drawing is 25 mm.
2. The actual height is 20 m, which we need to convert to mm for consistency. Since 1 m = 1000 mm, we have:
   $$
   20 \, \text{m} = 20 \times 1000 \, \text{mm} = 20000 \, \text{mm}
   $$

3. Now, we can set up the scale as follows:
   $$
   \text{Scale} = \frac{\text{Actual Height}}{\text{Drawing Height}} = \frac{20000 \, \text{mm}}{25 \, \text{mm}} = 800
   $$

This means the scale of the drawing is $$ 1:800 $$.

Therefore, the correct answer is **1:800**.
The scale of the drawing is 1:800.

The height of a tower is shown as 25 mm in a drawing. The actual height is 20 m . What is the scale of the drawing? 1:250 1:800 \( 1: 500 \) \( 1: 400 \)
