2. 2019年北京師范大學版四年級數學下冊第一單元考試卷答案

解：S△ABF＝4√10/3

如圖,橢圓x²/8+y²/4＝1,則a＝2√2,b＝c＝2

橢圓左焦點F1(-2,0),右焦點F(2,0),直線l過點(0,1),與橢圓交於A(x1,y1)、B(x2,y2)兩點

●AF+AF1=2a＝4√2,BF+BF1＝2a＝4√2

L△ABF＝AF+BF+AB=8√2+AB−(AF1+BF1)

AF1+BF1⩾AB(當且僅當A,B,F1共線時取等號)，當l過點F1(-2，0)時，周長取最大值8√2

●直線l方程為x-2y+2＝0，與橢圓方程聯立，得：4(2y-2)²+8y²-32＝0→3y²-4y-2＝0

y＝2/3±√10/3

|y1|＝2/3+√10/3，|y1|＝-2/3+√10/3

●S△ABF＝½*(|F1F|*|y1|+|F1F|*|y2|)

＝½*|F1F|*(|y1|+|y2|)

＝½*4*(2√10/3)

＝4√10/3
