Answer:
The perimeter of the triangle is P=a+b+c
where a, b and c are sides of the triangle.
a=3 3/6 cm
b=9 1/8 cm
c=6 cm
Now a=21/6 cm, b=73/8 cm, c=6 cm
We have to take LCM in order to make the denominator same.
Now, the LCM is 48
21*8/6*8 + 73*6/8*6 + 6*48/48
168/48 + 438/48 + 288/48
= 894/48 cm
