we have to find area bounded between lines y=1 and y=3 and y=2x+4 AND Y-AXIS


y=1 cuts the curve y=2x+4 at the point (-3/2, 1)


y=3 cuts the curve y=2x+4 at the point (-1/2, 3)


when we draw graph for these four curves thers ian traingle and rectangle. we have to compute those two surface areas.


 


reactangle has sides (0,1) (0,3) (-1/2,1), (-1/2,3)


so area = 2*1/2 =1


vortices of triangle (-3/2,1)  (-1/2,1), (-1/2,3)


area of traiangle= 2*1*1/2 =1


total area =2 units
