Sounds difficult

In a rectangle ABCD, O is any pt. inside it and its distance from the 4 corners is as shown in fig. Then find the sides of the rectangle.

How is this going to help? We can just get the value of x, nothing else.

Great, that's a start. What can we do next?

If X, Y are the projections of O onto AB, BC, can we find AX, XB, BY, YC?

@Calvin Lin Sir, does projection mean perpendicular? Well, I m not able to form equations.

@Agr Amul Yes. "The Projection of P onto AB is X" means "Drop a perpendicular from P to AB, intersecting AB at X".

Write out the equations of Pythagorean theorem. For example, \( XB^2 + BY^2 = OB^2 \). You should have 4 equations. Does that help you solve for the sides? Why, or why not?

Note: I am not claiming that there is a unique set of solutions. I'm merely guiding you down what is the next sensible / logical step to take. It is not guaranteed that this must lead to a solution.

@Calvin Lin This, initially i thought would help; but its not doing any good to this question. Kindly suggest me something else, sir.
