The area of the quadrilateral for the given vertices are 34 square units.
Step 1: Given data
Vertices of quadrilateral are given as (-9,0), (-8,6), (-1,-2), and (-6,-3).
Step 2:
To find
The area of the quadrilateral for the given vertices.
Step 3:
Formula used for the area of quadrilateral.
Area of quadrilateral
Name the vertices
Substitute those values in the above formula,
We get, Area of quadrilateral
Area of quadrilateral
Area of quadrilateral
While cross multiplying, we get
Area of quadrilateral
