Your triangle  DELTAPQR  seems strange.
Its perimeter is  24 cm.
Its side  PQ  is of 12 cm long.

Hence, the sum of measures of two others its sides is 12 cm.

It is degenerated triangle.

The linear measurements are in proportion between the two triangles.

AB%2FPQ=32%2F24

AB%2F12=32%2F24

AB%2F12=4%2F3

AB=12%2A4%2F3=16
