The vertices of a convex pentagon are (-1, -1), (-3, 4), (1, 9), (8, 5) and (3, -1). What is the area of the pentagon?

Take area of   FGIH =  (10) (11)   = 110

 

Subtract  areas of  the right triangles  (1/2) [ (4*5 ) + (5*2) + (6*5) + (7*4)  ]  =  44

 

Area of pentagon =   110   -  44  =      66
