Answer:

36 inches

Step-by-step explanation:

Perimeter of the larger triangle: P1

Perimeter of the smaller triangle: P2

It's probably a right angle triangle. Verifying through pythagoras theorem:

20² = 12² + 16²

400 = 144 + 256

P1 = 20+12+16 = 48

P1/P2 = side1/side2

48/P2 = 16/12

48/P2 = 4/3

P2 = 48 × 3/4

P2 = 36
