I AM TRYING SOMETHING NEW AND CREATIVE SO PLEASE BEAR IT AND DO INFORM AM I CORRECT OR NOT!!!!!!!!!
NOW I AM ASSERTING THAT THE AREA WILL BE MINIMUM IF BOTH THE LINES ARE PARALLEL
i.e SLOPE OF ax+by=1 SHOULD BE tan-14/3
SO
THIS IS MINIMUM WHEN a/b=4/3 AND IT SHOULD BE PROPORTIONAL SO a=8 AND b=6
and the area =1/2ab
=1/2X8X6=24
