This is a great book, well presented and with very easy explanations, thank you Mary, it is much appreciated; I have recommended this book to many.
In answer to Steve’s query (other reviewer), yes, you are correct, there is a transcription error, it should read:
AC = 5, AB = 8, CD = 6, BD = ?. The product of the diagonals is 10×10.5 = 105
Therefore, it should read 105 = (AB)(CD)+(AC)(BD) …. AD and BC, as included in the book, are the diagonals.
Therefore, the answer should be 11.4.
When producing a body of work such as this, there will always be small errors overlooked by the proofing process … it just keeps you on your toes though. It is better to question when you find something you’re not sure of, rather than accept it as fact … quite a good mantra for life really
