Anna Milbanke

Annabella Milbanke (11th Baroness Wenthworth) married the notorious Lord Byron on 2 Jan 1815, after refusing his first proposal of marriage in 1812. Byron called her his princess of parallelograms, since she was interested in mathematics. She tried to reform him, but her efforts were in vain. Byron treated her badly and amost certainly had an incestuous affair with his half sister Augusta (possibly he was the father of one of Augusta's children). With the help of her parents Annabella obtained a divorce in 1816. By that time their daughter Ada Augusta was just a few months old.

Tennessee

The area formula is the same for a rectangle, square, and a parallelogram because, all three formulas multiple the length times the width. Tennessee is the an example of a parallelogram. The formula of finding the area of a parallelogram is area equals base times the height. The base is 495 and the height of Tennessee of 57 radical 2. Multiply them together and you get 39,902 square miles. Tennessee actually is 42,146 square miles.
