I cut myself a rectangle out of a chessboard. (All cuts were along the square lines, so the rectangle has integer sides.)

Were I to tell you either its area, or its perimeter, or the length of its diagonal, you wouldn't be able to determine the dimensions of the rectangle.

What's its size?

(In reply to the Solution by Charlie)

I did it a similar way, but I disagree with saying that "all of these have non unique perimeters" becuase the 1x1 and 8x8 pieces have unique ones.
