Solution: (1) connects BD, and the area of △BCD is:14× 6 ÷ 2 = 42; The intersection a is the EF//x axis, and the intersection y axis is f, e (- 1 1, 8). Then the area of trapezoidal BEFD is (8-2+6)× 1 1÷2=55, and the area of △ABE is (8-2) (11-2) ÷ 2 = 27; △ The area of △AED is 2×8÷2=8. So the area of quadrilateral ABCD is: 42+(55-27-8)=62. (2) Calculate according to the method of the previous question.
