Yes, there could be a misprint in book.Right angle has to be assumed here.But not necessarily isoseceles triangle !!

Because, for triangle OBC it shows the two sides are nothing but radii.

So the formula can be reduced to 1/2 alt*base=50
=> 1/2*r*r=50

Sandeep, the formula you have posted can not be used because one variable in the formula is the base of the triangle and the other is one of the equal sides.

Amit, I also think this is an error on part of PR. This problem is from one of their tests and not from the book.
