BunuelCan you explain if the formula Side of A/Side of B = (Area of A/Area of B)^2 would be applicable to this case? IF not, why? And if yes, how? PS: Your solution is much simpler, but just in case...

Does anyone have a picture explanation? I am not seeing the hint indicating that ABO triangle is 1/2 the area of ABC

In this case, wouldn't the value of AC be sqrt 2.
If so, it would then lead AO = (sqrt 2)/2 (half of the base of isosceles triangle) Then BO = 1/2 Area of AOB = 1/2*1/2*(sqrt 2)/2
If we follow this approach, where we are still considering triangle AOB as half, why is the solution different from 1/4?
