I can do it with a pencil or a slide rule, but I prefer to use a small calculator. When I do that, I get an answer of 94.027 I know that can't be right, because 90 x 90 is 8,100. You always have to do a sanity-check on the answer you get to see whether it makes sense. There are two ways to get a garbage answer out ... put garbage in, or make a calculating error. In this case, I accidentally punched in '8841' instead of '841'. The square root of 841 is actually 29.

It is: 841 square mm
