A、B两人位于东西朝向的大道上,相距6米,如图所示,在靠近B的区域,离大道2米处有一摄像机C,镜头可视角度为90°,此时B恰好位于视野边缘,而A需向东前进1米才能刚好出现在视野边缘;若A、B两人保持原位置不变,摄像机需往北移动_______ 米,再适当旋转镜头,使A、B两人刚好处于视野边缘.

【推荐1】如图,在平面直角坐标系中,直线
与x轴交于点A1,与y轴交于点A2,过点A1作x轴的垂线交直线
于点B1,过点A1作A1B1的垂线交y轴于点B2,此时点B2与原点O重合,连接A2B1交x轴于点C1,得到第1个
;过点A2作y轴的垂线交l2于点B3,过点B3作y轴的平行线交l1于点A3,连接A3B2与A2B3交于点C2,得到第2个
……按照此规律进行下去,则第2019个
的面积是________ .
