WebThe scale factor describes the size of an enlargement or reduction. For example, a scale factor of \(2\) means that the new shape is twice the size of the original. A scale factor of \(3\) means ...

WebFor example, to enlarge a shape with the scale factor of two, the length of all sides would be multiplied by two. Since the new shape is similar, all of the angles would be the same size. WebThe dimensions of our scale drawing are 6 by 8 which gives us an area of 48 square units. Notice when we found the new dimensions we multiplied the 3 and 4 EACH by the scale factor. So the new area could be found 3 x 4 x scale factor x scale factor. 48/12 = 4 …

WebScale factors are the ratio of two corresponding measurements on two similar figures. It is used in scaling and isn't constrained to 2D shapes. You can also use a scale factor with 3D shapes. If you have the scale factor, you can convert a measurement into another similar figure's measurements. An example of this in use is when you're changing ... WebExample 3: You can also use scale factors to find out the original measurement of a shape. Just use the inverse of multiplication, which is division.
