The scale factor is 11. You can also use scale factors to find out the original measurement of a shape. Just use the inverse of multiplication, which is division.
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.
A scale factor is a ratio between two corresponding sides of similar shapes. A scale factor describes how much a shape has been scaled up or down. To scale a shape up or down, you multiply every side length of a shape by the scale factor to increase or decrease the size. The sizes of the angles do not change.
The scale factor determines the degree of enlargement or reduction in a dilation. It represents the ratio of corresponding lengths between the original figure and its dilated image. We compare the corresponding lengths of any two sides or segments to find the scale factor.
What is a scale factor? A scale factor describes how much a shape has been enlarged. We multiply every side length of a shape by the scale factor to enlarge it. The sizes of the angles do not change. Enlarging a shape by a scale factor greater than 1 will make the shape bigger. E.g. Shape A has been enlarged by scale factor 2 to give shape B .
A scale factor is the ratio between the size of an original and final object that vary only in size. For example, the penguin shown on the left below is 3 times larger than the penguin on the right. The factor we would scale the larger penguin by to get the smaller penguin is the scale factor.
