Look at the graph here :  https://www.desmos.com/calculator/fgiku8nsic

 

This triangle  will have a base of 6

 

The  apex of the  triangle is   (1.8, 3.4)

 

The distance  between this  point and the  y axis is the  altitude of the  triangle and  is  just  1.8  units

 

So.....the area is 

 

(1/2) ( 6) (1.8)  = 

 

3 * 1.8   =

 

5.4 units^2
