Step-by-step explanation:
If we place the books using their width on the length of the book shelf then
each book occupy the length : 9.3* 10^-2 meter on the length of the book shelf .Here width of book and length of book shelf is in same unit , that is meter . so we do not have to do any work with changing the unit .
number of books = length of the book shelf divide by width of the book
That is : 1.865 x 10 ^1 divide by 9.3x 10^-2 = 200.53
Because number of books placed can not be a decimal number so we would place only 200 books
Answer :200 books . Option A is correct .
