35
since m and n are the midpoints of ab and ac resistively 
then ,bc=2mn=16
since m and l are the midpoints of ba and bc respectively 
then, ac =2mn =10 
then,nc =1/2 × 10 =5
similary, mb=6 
then ,perimeter=nc+mb+mn+bc=5+6+8+16=35

Step-by-step explanation:
we know that
A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

where
a_n---->  term of the sequence
 term of the sequence
r ---> is the common ratio
a ---> the first term of the sequence

substitute

For n=12
