The length of the building on the scale drawing is found as 16 centimeters.
Describe the term scale factor?
- The ratio of the scale of an original thing to a new object that is a representation of it but of a specific widths is known as a scale factor (bigger or smaller).
- Scale factor ratios can be written as a colon, 1:2, or as a fraction, 12. A ratio calculates the difference between two values.
- However, that ratio isn't a scale factor, thus you could not build a ratio for left-handed pupils to all students.
For the given data in the question-
Dimensions of the building;
- Height of 125 meter
- length of 80 meters.
Dimensions of the drawing of the building;
- height is 25 centimeters
- Let the length be 'x'.
Thus, taking ratios of Height to length
125/80 = 25/x
On simplification;
x = 80 x 25 / 125
x = 16
Thus, the length of building on the scale drawing is found as 16 centimeters.
