A woman has a garden path 2 m wide ,with a hedge on either side.The path spirals into the middle of the garden .One day the woman walks the length of the path,fishing in the middle .Ignore the width of the hedge and assume she walks in the middle of the path .How far does she walk?
请具体地说说为什么吧！
为什么是9+8+8+6+6+4+4+2+2=49呢？9是哪里来的？8是哪里来的？6是哪里来的？4是哪里来的？2是哪里来的？说清楚点行吗？

是49m,因为是沿小道中心走,所以以人为中心,路的两边各留有1m,因此第一个直道是9m,(10-1)第二个直道为8m(9-1),第三个直道也是8m(9-1),最右边的第四个直道为6m（10-1-1-1-1）,依此类推即为9+8+8+6+6+4+4+2+2=49了.
64m
49m,题目是说一个女的从这个小道走过，小道两边都有围栏，走小道的中间路线，小道宽2m,最外围长10m，计算式9+8+8+6+6+4+4+2+2=49 ,我是这么想的，不知道对不对
62 或者 64 题目没说清楚
49
