解答：

每个多边形包含的方格数可通过把多边形分成单位正方形和边长为 $1$ 的直角三角形，再相加得到。

单位正方形面积算作 $1$ ，三角形面积算作 $.5$ 。

$A$ 的总面积为 $5$ ， $B$ 为 $5$ ， $C$ 为 $5$ ， $D$ 为 $4.5$ ， $E$ 为 $5.5$ 。

所以正确答案是 E。

The number of boxes enclosed by each polygon can be obtained by dividing the polygon into unit squares and right triangles with sidelength $1$ and adding up their values.

The unit squares count as $1$ and the triangles count as $.5.$

$A$ has a total area of $5,$ $B$ has $5,$ $C$ has $5,$ $D$ has $4.5,$ and $E$ has $5.5.$

Thus, E is the correct answer.
