Answer:
Let A(-4,-2) , B(-3,-5) ,C(3,-2) , D(2,3)
Join diagonal BD
In triangle ABD
By using formula
1÷2(x1(y2-y3)+x2(y3-y1)+x3(y1-y2)
Put x1=-4 ,x2=-3, x3=2 and y1= -2 , y2=-5 ,y3=3
Then we get triangle ABD=11.5.
Similarly in triangle BCD by using formula put x1=-3,x2=3,x3=2 and y1 =-5,y2=-2, y3=3
We ge triangle BCD= 16.5
Area of quadrilateral ABCD=11.5+16.5
=28.0 means 28.
