    [(5*12)/2 ]+ [(9*12)/2] + [(16*12)/2]= 180

    so the answer is non of them!

    How can the perimeter be 180 when already the sum of 3 sides given is 52..the fourth side cannot be 128????!
    answer is 72..cuz BC=20

    E
    the right hand side is forming a right triangle, so that 4th side will be 13m & then the perimeter comes out 2 b 65, so the answer is none of the above

    The answer is 72...Another side of the diagonal is 20 units...So adding all we get 72...

    answer: C
    draw a perpendicular from point A onto seg DC..let the point on seg DC be F...triangle ADF is a right angled triangle and is a 13-12-5 traingle(AF=BE=12)..so DF=5,FE=AB=9 and DC=30...so EC=16...now,BEC is another right angled triangle...now find out BC as BE=12 and EC=16...BC=20...perimeter is equal to 9+20+30+13=72...hope this clears everybody's doubts...
