Mathematics - Area Under Curves Question with Solution | TestHub

We have,$z=5x+4y$
Subject to contraints$y\le 2x,x\le 2y,x+y\le 3,x\ge 0,y\ge 0$
On taking given constraints as equations, we get the following3 graph.

Intersecting point of line$y=2x$and$x+y=3$is$A\left(1,2\right)$and intersecting point of line$y=2y$and$x+y=3$is$B\left(2,1\right)$
Here OABO is the required feasible region whose corner points are$O\left(0,0\right),A\left(1,2\right)$and$B\left(2,1\right)$
