A gentleman had a sitting room with only one window in it -- a square window, three feet high and 3 feet wide.   Now he had weak eyes, and the window gave off too much light.   So, he called for the builder, and told him to alter it, so as to give half the light.   Only he has to keep it square -- he has to keep it 3 feet wide -- and he has to keep it 3 feet high.
How did he do it?
Remember, he wasn't allowed to use curtains, or shutters, or colored glass, or anything of that sort.

You can see that it is half the area of the original window:

The original window has an area of 9 square feet and the altered window has an area of 9/2 square feet.
