On each side of a unit square,an equilateral triangle of side length 1 is constructed.On each new side of each equilateral triangle,another equilateral triangle of side length 1 is constructed.The interiors of the square and the 12 triangles have no points in common.Let R be the smallest convex polygon that contains R.What is the area of the region that is inside S but outside
A 1/4 B √2/4 C 1 D√3 E 2√3
Let R be the region formed by the union of the square and all the triangles,and let S be the smallest convex polygon that contains R.

On each side of a unit square,an equilateral triangle of side length 1 is constructed.On each new side of each equilateral triangle,another equilateral triangle of side length 1 is constructed.The interiors of the square and the 12 triangles have no

where is the S?

Let R be the smallest convex polygon that contains R?

选b：

理由,在等边三角形的外围在做等边三角形时,有两种状态,如图中所标1,2两种状态,像搭积木那样考证,只有如图所示的多边形面积S最小,因为除去正方形及12个三角形的面积之外,只多余了一个等边三角形的面积,其余的放法怎么都会使得多边形的面积除去固定值之外,比一个三角形的面积多.所以,本题所求的面积：S之内,R之外的面积是一个等边三角形的面积：B

按这个题的叙述。。。选项里没有我作出的答案。。。 你看看题哪里是不是搞错了。。。。？ 我想了好久啊。。。。。、 可能我木有做对 但是交流一下或许可以对你提供帮助。。。。
呃 你改了。。。
但是我还是没有作出选项里的答案来。。。。 我算的是3-√3...
