Will mark a book is about 9.3 × 10^-2 meters thick. a bookshelf is about 1.865 × 10^1 meters long. about how many copies of this book will fit on the bookshelf? a.200 books b.20 books c.498 books d.17 books

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 .

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
