I think I saw that you tried to include that your units were in inches. this is not a metric unit to start. convert inches to centimetres. then multiply the length by the width to get your answer in cm^2, a metric unit

Inches or centimeters
The practical unit of area for the front cover of a book is typically measured in square inches or square centimeters. This measurement helps to determine the dimensions of the cover, which commonly includes height and width. For example, a standard novel might have a cover area of about 6 inches by 9 inches, resulting in an area of 54 square inches.
You would typically use centimeters (cm) or millimeters (mm) to measure the width of a book. These units provide a more precise measurement for smaller objects like books.
Try using a triple beam balance, or a electronic scale. The units to measure the mass of the book would be in grams.
centimeter
To find the area of a book cover in metric units, the most appropriate unit to use would be centimeters. The formula for finding the area of a book cover would be: length x width.
meters2
If it's a standard book, the standard units would probably be cm2.
Square centimetres and square metres are measures of area in 2-dimensional space: they cannot be used to measure the length of a book cover which is a 1-dimensional measure.
(length of the cover) times (width of the cover) is.
The area of a book cover would depend on the dimensions of the cover. To find the area, you would multiply the length by the width of the book cover. Formula for area of a rectangle is length x width.
