Answer:

10

Step-by-step explanation:

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

scale factor = $\frac{PQ}{XY}$ = $\frac{3}{6}$ = $\frac{1}{2}$

That is the sides of Δ PQR are half those of Δ XYZ, thus

The perimeter of Δ PQR is half Δ XYZ, that is

perimeter of Δ PQR = $\frac{1}{2}$ × 20 = 10
