You can put this solution on YOUR website! This is only a start, not a finished solution:
Imagine a point in quadrant one, (p,s) on the circle.
The three other points for the rectangle are (-p,s), (p,-s), and (-p,-s). Area of this rectangle would be .
Your circle containing those four corners of the rectangle is radius 5,
.
Those seem to be two equations in two variables. No real need to pick the new variables p and s, so just go back to x and y, since they still are variables.

.....you should continue...............
