Question

The square on the right is a scaled copy of the square on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form. 39/2 13 13 39/2

Answer 1

Similarity ratio is also called the scale factor and is defined by the ratio of the lengths of the sides in two similar polygons:

`\begin{gathered} SF=\frac{lenght\text{ of right square}}{\text{lenght of left square}} \\ SF=((39)/(2))/(13) \\ SF=(3)/(2)\text{ or 1.5} \end{gathered}`
