Using the method of integration, find the area of the triangle ABC, coordinates of whose vertices are A (4, 1), B (6, 6) and C (8, 4).
we have A(4,1), B(6,6) and C(8,4) as the vertices of a triangle ABC
Then equation of AB is
Equation of BC is
Equation of CA is
clearly , Area of Area of liapezium ABDE + Area of trapezuim BDFC - Area of liprizium ACFE
Hence area of
