Q. You need to print a document of the area 216 sq cm. Condition is 3 cm margin is to be left at both top & bottom and 2 cm at the sides. What is the optimized size of your paper?

• let us consider it is a rectangle.
  so area=24*9=216sq.cm
  now (24-3*2)*(9-2*2)=18*5=90sq.cm

• Lets say, the page is a rectangle with length 18 and width 12
  So, total area = 216
  Now, removing 3 cm from both top and bottom would remove area = 2*3*12 = 72
  Now, removing 2 cm from both the sides would remove area = 2*2*(18-6) = 48
  So, total area removed = 72+48 = 120
  Remaining area = 216-120 = 96

• Prime factors of 216 = 2^3 * 3^3 = 8 * 27
  Now the Required Size of Paper = (8 - 2*2) * (27 - 3*2) = 4 * 21 = 84

• if paper is rectangle with l=18 & w=12
  so area=12*18=216
  margin area=18*3+2(12*2)-2(2*3)(corner)=90
  then optimized size=216-90=126
