What is the difference between scale and scale factor?

The scale gives the ratio that compares the measurements of the drawing or model to the measurements of the real object. Scale factor is a scale written as a ratio without units in simplest from.


How is the scale factor the same as the ratio of the area?

The scale factor between two similar figures is the ratio of their corresponding linear dimensions (lengths). When calculating the area of similar figures, the area ratio is equal to the square of the scale factor, since area is a two-dimensional measurement. Thus, if the scale factor is ( k ), the ratio of the areas is ( k^2 ). This relationship illustrates that while the scale factor pertains to linear dimensions, the area ratio reflects the effect of that scaling in two dimensions.


Does the same relationship between the scale factor of similar rectangles and their area apply for similar triangles?

Yes, the same relationship between the scale factor and area applies to similar triangles. If two triangles are similar, the ratio of their corresponding side lengths (the scale factor) is the same, and the ratio of their areas is the square of the scale factor. For example, if the scale factor is ( k ), then the area ratio will be ( k^2 ). This principle holds true for all similar geometric shapes, including rectangles and triangles.
