Hence the perimeter of the field is
- 50 m
- 64 m
- 72 m
- 84 m
- None of the above

[(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
answer is c
answer is none of the above
answer is c as sum of three sides is 52 & the fourth side is 20
YA CORRECT ANS IS C 72
SALIMA IS ABSOLUTELY CORRECT
ALSO CONGRATS RADHA, FOR CORRECT ANS
k
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...
how that diagonal value is 20.i think it is wrong.the ans is none of the above.
C
C
its 64 i think
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...
