如图，在平面直角坐标系中，O为坐标原点，△ABO的边AB垂直与x轴，垂足为点B，反比例函数y= $\frac{k}{x}$ （x＞0）的图象经过AO的中点C，且与AB相交于点D，OB=4，AD=3，

如图是一个组合图形，请用两种方法计算出这个图形的面积（单位：米）

There is a new park near Andy's home. It's fine today. Andy and his family are in the park now. On their left, there is a café. On the right, there is a big lake. There are many flowers and trees around the lake. There's a small hill behind the lake. Near the lake, there are two signs（标记）. One says, "Don't swim in the lake."But you can go boating on the lake. There is a beautiful garden in the middle of the park. There are green grass and beautiful flowers in it. There are some small shops between the lake and garden. The park is so nice. Andy and his family like it very much.
