when you go to the doctor ,you are supposed to make an a__________

When you go to the doctor,you are supposed to make an __appointment__.预约的意思
设小三角形任意一个边长为a,以该边所作的高为x*a(任何两个值一定可以用其中一个值的倍数来表示,比如a为3,如果高是7,那么可以表示为7/3*a),则大三角形对应边长为d,所作高必然跟小三角形内对应两点距离的倍数关系相同（相似）,设为x*d.
小三角形面积为 0.5 * a * x*a (二分之一底乘以高）
大三角形为 0.5 * b * x*b
比值为 a平方/ b平方 = 2:7
说明a/b = 根号 2/7
则大三角形的高也为小三角形高的根号7/2倍
再问：抱歉，题目打错了。图没错，题目应该是：已知三角形ABC的面积是根号3的等边三角形，三角形ABC与三角形ADE相似，AB=2AD，角BAD=45度，三角形AEF的面积是多少？（结果保留根号）若有帮助，将选为满意答案，谢谢！
再答：那结果也没多大区别啊。。。我已经证明给你看了，相似三角形的面积比等于边长比的平方。如果ABC和ADE对应边AB=2AD，就是边长比为1:2，那么面积比就是1:2的平方为1:4.然后大三角形面积是根号3，那小三角形的面积应该是（根号3）/4
再问：是求三角形AEF的面积，而不是三角形ADE的面积。谢谢！
再答： EF和FD的比例很容易证明是15/45=1/3，那么AEF和AFD的面积比就是1:3（等高）。而小三角形的面积是（根号3）/4，那么AEF的面积就是[（根号3）/4]*(3/4)。
