The point of intersection of ( x1+yb ) = 1
And y=x would be (1×b(1+b),1×b(1+b)).
The area of triangle AOC (0,0), (1,0) and (1×b(1+b),1×b(1+b)), would be 12×12b(1+b)
The area of triangle BOC (0,0), (0,b) and (1×b(1+b),1×b(1+b))., would be 2×12×12b(1+b)
Since, area of ΔAOC is twice the area of ΔBOC
Therefore,
12×12b(1+b) =2×12×12b(1+b)
⟹1=2b.
coordinate of C=(1b(1+b),1b(1+b)).
Therefore coordinate of C is (13,13).
