In a quadrilateral ABCD,

AB is parallel to DC and AD is parallel to BC. Find the perimeter of ΔCOD if the diagonals of the quadrilateral intersect each other at pointOand AC = 20 in, BD = 20 in, AB = 13 in

Can You Add the Answer,

1 answer

The diagonals bisect each other.
Therefore, DO = 0C = 20/2 = 10 in.
CD = AB = 13 in.

P = DO + OC + CD = 10 + 10 + 13 = 33 in.
