Answer:

55

Step-by-step explanation:

ΔVMW ~ ΔPMN, because as their bases are parallel, it means their angles are equal.

===============================================================

Finding the scale factor :

⇒ VW : PN

⇒ 6 : 15

⇒ 2 : 5

==============================================================

Finding WN :

⇒ MW : WN = 2 : 5

⇒ 8 : WN = 2 : 5

⇒ 8/WN = 2/5

⇒ WN = 8/2 × 5

⇒ WN = 20

=============================================================

Perimeter of ΔPMN :

⇒ Perimeter = MP + PN + MW + WN

⇒ Perimeter = 12 + 15 + 8 + 20

⇒ Perimeter = 27 + 28

⇒ Perimeter = 55
