Answer: The perimeter of each book is: " 36 in. " .
__________________________________________________
Step-by-step explanation:
__________________________________________________
Note that the given units are all in "inches (in.)" .
Use the formula for the "perimeter of a rectangle" ;
{which happens to work for a "square" as well;
since a "square" is a rectangle.}.
__________________________________________________
This is based on the assumption that the book is shaped like a
"rectangle" (or "square" —which is a rectangle).
__________________________________________________
The formula for the Perimeter of a rectangle is:
P = 2 L + 2 w ;
in which:
P = the perimeter of the rectangle;
for which we shall solve; [in "inches (in.)" ] ;
L = the length of the rectangle = 10 in. (given) ;
w = the width of the rectangle = 8 in. (given) .
___________________________________________________
Now, plug the given values for the "length (L)" and the "width (w)" ;
as follows:
___________________________________________________
P = (2 * 10 in.) + (2 * 8 in.) ;
P = (20 in.) + (16 in.) ;
P = 36 in.

Answer: The perimeter of each book is: " 36 in. " .
