题目内容：

请翻译As shown in the following diagram,there is a triangle ABC.Now we extend the length of Side AB to Point D,which makes BD=ab; while we estend the length of Side AC to point E,which makes CE=2AC;THUS we can get a bigger triangle ADE.Now please calculate the area ratio of Triangle ADE to Triangle ADE Triangle ADE to Triangle ABC.

数学题啊,
根据下面的图,三角形ABC.现在把一条边AB延伸至D点,使得BD=AB,再延长AC至E点,使得CE=2AC.我们得到了一个更大的三角形ADE.现在请计算三角形ADE与ABC的面积的比率.
