MAlinear programming

hi there guys,could someone care to explain to me,what this actually means

when the iso-contribution line is drawn the point furthest away from the origin
along the iso-contribution line will be the point where we will achieve total
maximisation....

i am thinking the point will definately be within the feasible region or the polygon whichever way u want to call it.....but according to the statement above
do they mean that it will be along the iso-contribution line but still within the
feasible region?????????help
