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.

三角形ABC如下图所示。现在延长AB边到点D,使BD=ab;延长AC边到点E,使CE=2AC;最后形成三角形ADE。请计算三角形ADE与ABC的面积之比。
如图,三角形ABC,延长AB到点D,使得BD=AB;同时延长AC到点E,使得CE=2AC;这时我们得到一个大三角形ADE。请计算。。。(后面是不是输入有误。。我看不懂了)
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.
如图所示,在下图中,有一个三角形ABC。现在我们延伸长度的侧AB型血输给D点,使BD = AB;我们estend边的长度交流点E,使CE = 2 AC;这样,我们就可以得到一个更大的三角该。现在请计算三角形的面积比该三角形三角形对,该该三角形ABC。
