1) measurements of angles PQR, QRP, RPQ are x deg, 2x deg, 3x deg respectively

2) altitude of tri PQR from Q to PR is 4.

OA is C, but I don't get it.

1) tells u only angles - insuff.
2) tells u the "height" (if the traingle is draw with Q at the top)

from 1 you can see that angles form a 30-60-90 triangle i.e a right triangle. and from 2 it shows that PQ is 4. so since its a triangle with ratios 1:sqrt(3):2 perimeter can be calculated

so ans = C
