Question

if (1,2) (5,8) (3,4) & (2,5) are vertex of a quderilateral taken in order find the area​

Answer 1

Step-by-step explanation:

area of quadrilateral=

area of two triangles formed by one of its diagonal.-(1)

A(1,2)=x,y

B(5,8)=x2, y2

C(3.4)=x3,y3

D(2,5)=x4,y4

area of triangle ABC=1/2(x1(y2-y3)+x2(y3-y1)+x3(y1-y2))

=1/2(1(8-4)+5(4-2)+3(2-8)

=1/2(4+10-18).
