Answer:
Option B is correct.
Explanation:
Figure is attached with marking of vertices.
from figure ∠A and ∠D are right angle
So, we can break the given figure in to a triangle BEC & a Rectangle ABCD
We know that opposite side of the rectangle are equal. So,
CD = AB = 16 cm
So the Perimeter of the given figure = AB + BE + EC + CD + AD = 16 + 10 + 10 + 6 + 12 = 64 cm
Therefore, Option B is correct.
