A square that is confined to the first quadrant of the Cartesian Plane has ones of its sides start at the Point ( u, 0) Pass through the Point (1, 8 ) and end at the point (o, v) where u>l and v > 8 ( 0 , V ) (1 , 8 ) ( 4; 0) Pol ( a) show that A= usto (b) Find the Critical value of A (( ) determine the nature of the critical valued's ( d) what is the smallest Possible area of the square and for what values of us and v does it occur
