(1) we dont know the values of any sides....not suff..
(2) we dont know the sides of any triangle or any info about AD is any median,height or simply dividing the sides.....not sufff...

if triangle is 6-6-6 equilateral triangle then perimeter will be different from a isosceles triangle having sides 5-5-8
thus insufficient to answer about perimeter.
