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
Most like a vernier caliper for accurate readings
A phone book has 3 dimensions, and they are length, width, and thickness. It has 6 faces, and they are the front, back and the four "sides" or "edges" of the book. These are all faces, and the surface area will have to account for all the faces. Let's break it down and find that surface area. Picture the book on a table in front of you with the back of the book (called the spine) on your left. The book's cover is length x width, and you have a front and back cover. Take that length x width x 2 to find the area (in square units) of the front and back covers. Now all you have to do is take the thickness x length x 2 to find the area of the back of the book and the front of the book, and then take the thickness x width x 2 to find the area of the bottom and top edges of the book. Add the three numbers and you have the surface area of the book. Want an example? Let's have at it. A 4 inch thick phone book has covers that are 8 by 11 inches. The covers (both of them) are 8 x 11 x 2 = 176 in2 for an area. The front and back sides or edges of the book have an area that is 4 x 12 x 2 = 96 in2 for an area. The top and bottom sides or edges are 4 x 8 x 2 = 64 in2 for an area. We have 176 + 96 + 64 = 336 in2 for the surface area of that phone book. Simple once you break it down and think it through.

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.
centimeter
If it's a standard book, the standard units would probably be cm2.
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.

(length of the cover) times (width of the cover) is.
No why would it
The 'area' of a telephone book - is simply the geographical coverage. Some books only cover a single town - others cover whole counties.
Multiply width by length to get the area. The answer would be 80.51 square inches.

Inches or centimeters
well, i know that a book jacket is kind of like the cover of a book. therefore, a book jacket ad would probably be the cover of a book in means of advertising. (for example, a magazine cover. a mag cover offers advertisement to articles) -yours truely, me :].
