To find the scale factor for the drawing, we can compare the measurement in the drawing to the actual measurement.
The scale is given as 8 centimeters = 1 meter. To find the scale factor:
1. Convert the actual measurement (1 meter) into centimeters, since the drawing is in centimeters.
- 1 meter = 100 centimeters.
2. The scale ratio can now be expressed as:
- Drawing measurement : Actual measurement = 8 cm : 100 cm.
3. To express this as a simplified ratio, we can divide both numbers by the greatest common divisor, which is 4:
- \( \frac{8}{4} : \frac{100}{4} = 2 : 25 \).
Thus, the scale factor used in the drawing is \( 2 : 25 \).
