Five circles are arranged in the following fashion ( Two rows of 3 circles in square arrangement with one end circle removed from the top row ). Circles are of same diameter and touching adjoining circles as per the diagram. Draw a line passing through A ( Centre of the first circle on the bottom row ) in such a way that it divides the five circles into two equal areas.

re(2): Equation spoiler by vswitchs)
You are right, of course. Silly me! Somehow it's a lot more
obvious to me if the radius is 1, though. There is no point in making
the radius anything but 1, actually, since it can always be 1 "unit,"
whatever a "unit" might be (such as 2.7693 feet).
