Frequently Asked Questions
What is a linear scale factor?
A linear scale factor is the multiplier applied to every dimension of a shape when resizing it while keeping its proportions the same.
What is the scale factor for a 10 by 5 rectangle resized to a width of 15?
The scale factor is 3, giving a new length of 30, since every dimension is multiplied by 3.
How does area change when a rectangle is scaled?
Area scales by the square of the linear scale factor, so a scale factor of 3 makes the area 9 times larger, not just 3 times larger.
