Question

If the rectangle on the right is the pre-image and the one on the left is the image, whattt is the scale t is the scale facfor?

Answer 1

Let's begin by identifying key information given to us:

The rectangle on the right has a dimension of 8 by 4

The rectangle on the left has a dimension of 6 by 3

The scale factor is given by the ratio of the image to the pre-image:

$\begin{gathered} sf==\frac{\text{Smaller Length}}{Larg\text{er Length}}=\frac{6}{8}=\frac{3}{4} \\ sf=\frac{3}{4}=0.75 \\ sf=0.75 \end{gathered}$

Therefore, the scale factor is 0.75
