Respuesta :
If it's a square, both sides are equal. If one side is 9 inches, then the other side is 9 inches. When you are finding area of a quadrilateral you multiply the two different lengths together. So 9in×9in=81in^3. (^3 means a tiny 3 up at the top corner of the number).
Sarah is lining a square tray with 1 inch square tiles the side length of the tray is 9 inches. Hence, She needs 9 tiles with 1 in side length.
