Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures.
A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller). For example, if we have a rectangle of sides 2 cm and 4 cm, we can enlarge it by multiplying each side by a number, say 2.
How do you find the scale factor?
The basic formula that is used for calculating the scale factor is,
Scale factor = Dimension of the new shape ÷ Dimension of the original shape.
In case, if the original figure is scaled up, the formula is written as,
Scale factor = Larger figure dimensions ÷ Smaller figure dimensions.
Example -
A scale factor is a number which multiplies (“scales”) a quantity. For example,the “C” in y = Cx is the scale factor for x. If the equation were y = 5x, then the factor would be 5.
The scale is shown as the length in the drawing, then a colon (":"), then the matching length on the real thing.
Example: this drawing has a scale of "1:10"
