A quadrilateral has four points A(0,1), B(1,-3), C(5,-2) and D(4,0) as coordinates What is the area of quadrilateral ABCD?
HOPE THIS HELPS!!
We can use something known as Pick's Theorem here
Lattice point = a point with integer coordinates
The area is given by
# Lattice points in interior of figure + ( # lattice points on boundary) / 2 -1 =
11 + 4/2 - 1 =
11 + 2 - 1 =
12 units^2
