在平行四边形ABCD中，AE=3分之2AB，BF=4分之3BC，AF与CE相交与O点，已知BC的长是16厘米，BC边长上的高是9厘米，那么四边形AOCD的面积是多少 ?
图形大致如下:
A D
E O
B F C
本人不胜感谢``
``````A-----------D
````````````````````-````````````-
```````````````````-````````````-
``````````````````E````````````-
`````````````````-``````O`````-
````````````````B--------F--C
上面的是图形```有关的长短根据题目里面的```
其中--是连接点的线,```是空格,因为不然会显示不出空格的.
