问题 单项选择题

如图,甲、乙、丙、丁四个长方形拼成正方形EFGH,中间阴影为正方形。已知,甲、乙、丙、丁四个长方形面积的和是32cm2,四边形ABCD的面积是20cm2。问甲、乙、丙、丁四个长方形周长的总和是()

A.32cm

B.56cm

C.48cm

D.68cm

答案

参考答案:C

解析:

S最里边阴影正方形=S四边形ABCD-

1/2(S+S+S+S)=20-×32=4,所以SEFGH=S最里边阴影正方形+S+S+S+S=4+32=36,所以,正方形EFGH的边长为6,周长为24。而如图所示,甲、乙、丙、丁四个长方形的周长和等于正方形周长的两倍,所以答案为24×2=48,选择C。

For more than one month, people in China have been worried about the fate(命运)of the 239 people, including 154 Chinese passengers, on board Air Malaysia Flight MH370. However, today no matter how sad we are and how many details(详细资料)that are not clear, it is certain that flight MH370 broke down in the Indian Ocean and no one on (44)it is alive. All the people in the world can do is to continue to look for the wreckage(残骸), talk with the Malaysian government for more information and accept the terrible fact.

People in China have been very disappointed with Malaysia Airlines these days. They do their best to show the Malaysian government that we will never give up knowing the truth. On the other hand, the number of Chinese people who choose to take a trip in Malaysia has been smaller and smaller. Many Chinese people including some famous movie stars say that they will never go to Malaysia any more.

At present, there’s a totally new expression coming out after this event. That is, “Don’t be so Malaysia.”45 People use it to describe someone who is unbelievable and likes telling lies to hide the truth.
