WSP Scale Factor
6th to 8th, High School
A common misconception is that when the dimensions of an object are doubled, the area is doubled, too. But this is not true! Use this applet to investigate how changes in the scale factor influence the ratio of perimeters and the ratio of areas between two figures.
Any button will toggle on/off the relationship between the two measurements above it.
When the dimensions of the object are doubled, what will happen to its perimeter and area?
