Using the method of integration find the area of the region bounded by lines:

2x + y = 4, 3x – 2y = 6 and x – 3y + 5 = 0


It is given lines if equations are 2x + y = 4, 3x – 2y = 6 and x – 3y + 5 = 0.


Thus, the area of the region bounded by the lines is the area of ΔABC.


And let us draw AL and CM perpendicular to x – axis.


Then,


Area (ΔABC) = Area ALMCA – Area ALB – Area CMB
