Question

a book contain 360 pages which measures 20cm by 14cm. every page has a blank margin 2.5cm deep along each short side and 2cm deep each long side. Find the total area available for printing.

Answer 1

"According to the question,

Length of printing area= 20- 2x2

                  = 20-4= 16.

Breadth of printing area= 14- 2x2.5

                   = 14- 5= 9.

So, printing area on each page= 16x9=144.

The book has 360 pages. So, as per the question,

Total printing area= 144x 360

              = 51840 cm2.

When converted into m= 5.184 m2. Thus,  the total area available for printing is 5.184m2."
