Question

quadrilateral m is a scaled copy of quadrilateral l. what scale factor takes quadrilateral l to quadrilateral m?

Explanation:

Step1: Recall scale - factor formula

The scale factor $k$ from a figure $A$ to a figure $B$ is given by $k=\frac{\text{corresponding side length in }B}{\text{corresponding side length in }A}$.

Step2: Choose corresponding sides

We can choose the pair of corresponding sides, say the sides of length 9.5 in quadrilateral $L$ and 7.6 in quadrilateral $M$.
$k = \frac{7.6}{9.5}$

Step3: Simplify the ratio

$k=\frac{7.6\div1.9}{9.5\div1.9}=\frac{4}{5}=0.8$

Answer:

$0.8$
