1)用直尺和圆规画出BC。

1.因为平行四边形对边长度相等 所以该边长为 4+3=7 
  又因为平行四边形的高=三角形的高=h=2S/低=2*3/3=2
  梯形面积=平行四边形面积-三角形面积=7*2-3=11

2.等差数列求和S=n(A1+A2)/2  
                        A1=10，A2=18，n=18-10+1=9
                所以S=126

销售和售后两个部门的性质差不多，都是以客户为导向。
销售是给客户一种超前的体验，让客户在使用之前通过你的介绍及你个人的魅力对公司及产品有个印象。
售后呢是实施和完善之前销售许诺的体验，让客户满意。
两者是一个连贯的流程。无论什么行业，都大同小异。

在我多年的经验看来，我建议你先做售后，原因是：
1.通过学习产品知识，对产品有一个全面的了解。
2.通过为客户服务了解客户需求，为销售打下基础。
3.如果有可能，建议你在生产车间工作一段时间。对生产工艺及产品特性的了解会让你的销售如虎添翼。
因为，没有对产品的充分了解，没有对客户需求的把握做销售很难。
即便你能忽悠出去产品，一段时间下来也只是修了个口头禅。终究成不了正果！
以上是我这些年的体会。
希望对你有帮助。
