Answer:
33 inches
Step-by-step explanation:
In a quadrilateral ABCD, AB ∥ DC and AD ∥ BC.
AC = 20 in, BD = 20 in, AB = 13 in.
We want to find the perimeter of ΔCOD if point O is the intersection of the diagonals.
Since AB ∥ DC and AD ∥ BC, the point O divides the diagonals into two equal parts.
|OD|=|BD|/2 = 20/2 =10inch
Similarly,
|OC|=|AC|/2 = 20/2 =10inch
Also,
AB=CD=13 inch
Therefore,
Perimeter of ΔCOD= |OD|+|OC|+|CD|
=10+10+13
=33 inches
