Given the points
A(0,-6), B(1,2), C(3,-3),D(-3,2) and E(-4,-2)
Area of the pentagon = Area formed by a polygon =
where a1 is the coordinate of vertex 1 and yn is the y-coordinate of the nth vertex etc.
Area of triangle formed by points below $x-axis,
Area=12bh=×−6=242=12 square unit
Angle subtended by BD at A=tan−1(8261)
