Answer:
We are given system with the following constraints:
x + y ≥ 80 ( it will be a line passing through (80,0) and (0,80) with shaded region above the line)
3x + 2y ≤ 360 ( it will be a line passing through (120,0) and (0,180) and shaded region will be below the line i.e. towards the origin)
x + 2y ≤ 200 ( it will be a line passing through (200,0) and (0,100) and shaded region will lie below the line i.e. towards the origin)
x ≥ 0
y ≥ 0
Clearly from the information we could see that the feasible region will lie in the first quadrant.
Since both x and y are greater than equal to zero.
The feasible region will be a pentagon abcde as could bee seen in the graph.
