Question

Find the area of the quadrilateral with
vertices (-1, -1). (-4,-2). (-5, -4) and
(-2, -3).​

Answer 1

Step-by-step explanation:

let A (-1, -1) B (-4,-2) C(-5, -4)and D (-2, -3)

vertices of the quadrilateral ABCD

Area of a quadrilateral ABCD= Area of △ABC+ Area of △ACD

By using a formula for the area of a triangle =

1/2[x1(y2-y3)+x2(y3-y2)+x3(y1-y2)]

Area of △ABC

1/2[-1(-2+4)-4(-4+2)-5(-1+2)]

=1/2[]
