Still taking prac exam right now, but this problem was driving me nuts, don't know OA yet, will post when I get done with exam.

The way I see it you can't solve this problem, there's a million different rectangles...I tried researching this on the internet, and everything I've read says there's an infinite number of solutions.

For a rectangle to be drawn in a circle, the diagonal of the rectangle= diameter of Circle=10

and in a rectangle of side c and d respectively we have c^2+d^2= l^2 where l is the diagonal...

In this case we side as \sqrt{a} and\sqrt{b} so a+b= 100....

Do share the OA
