A man is walking on the grass.He stars from A,and walks straight along to the east for three meters,then turn left for 120°,then walks straight along for 3 meters and turn left for 120° again.
How far away is he from A when he walks for 2005 meters?________
对不起，打错了一个词。第二句:he starts from A,不是翻译
答
结果是根号下28,也就是2根号7
他走了2005米,也就是走了111圈之后再走了7米.
他走的是正六边形,边长3米.能再讲细一点吗？我不会“根号”。。。。。
