**Find the number of ways of placing two knights in a chessboard that they can threaten each other.**

I tried to solve it like this but it was wrong because the answer was not among the four options.

I wrote the number of squares that that the knight can threaten on every square that we place it.Then multiplied the number of squares with the same number by the number in it.then calculated the sum of the results and multiplied it by two.But as I said it was wrong although I'm still sure its right.

thanks
