Each page of a book measures 12 inches by 8 inches. The cover extends beyond the shorter side one half inch in both directions.


What is the perimeter of the book’s cover in inches?

Verified Answer :

Based on the given condition above for the dimensions of the cover, the length is 12 inches and the new width is 9 inches. Perimeter is twice the sum of the dimensions, 
 
                                      P = 2 x (L + W)

Substituting the known dimensions,
 
                                      P = 2 x (12 in + 9 in) = 42 in

Therefore, the perimeter of the cover is 42 inches.
