  • Question
  • If a 36 cm thread is used to wrap a book, lengthwise twice and breadth wise once, what is the size of the book ?


  • Options
  • A. 288 sq.cm
  • B. 188 sq.cm
  • C. 144 sq.cm
  • D. 244 sq.cm

  • Correct Answer
  • 288 sq.cm 

    Explanation

    Length of the thread is 36 cms.
    length wise twice breath wise once then totally thrice.
    so 36/3 = 12.
    so length is 12 x 2 = 24 cms
    breath is 12 cms
    Area of the book = length x breath = 24 x 12 = 288 sq.cm
