The following area relationships are provided:
\(Area \ of \ △ABD : Area \ of \ △BDC = 1 : 1\)
Consequently, the area of \(△ABD = 54\)
\(Area \ of \ △EDB : Area \ of \ △ADE = 1 : 1\)
Therefore, the area of \(△ADE = 27\)
This indicates O is the centroid, dividing medians in a \(2:1\) ratio.
\(Area \ of \ △BEO : Area \ of \ △EOD = 2 : 1\)
Given this ratio, the area of \(△EOD = 9\)
The area of \(△EOD\) is \(9\) square cm.
