Answer:

QR = 5

Step-by-step explanation:

Since the parallelograms are similar, then the ratios of corresponding sides are equal, that is

[tex]\frac{AB}{PQ}[/tex] = [tex]\frac{BC}{QR}[/tex], then

[tex]\frac{9}{3}[/tex] = [tex]\frac{15}{QR}[/tex] ( cross- multiply )

9QR = 45 ( divide both sides by 9 )

QR = 5
