ms 41 and 42

 

Problem 41:

• First you should convert from mm to inches

  • 1 inch = 25.4 mm.
  • Width: $210\text{mm}$
  • Height: $297\text{mm=11.69 inches}$

• Then you calculate the resolution

  • Resolution = Width (in inches) × dpi × Height (in inches) × dpi.
  • For 200 dpi:
    • Horizontal resolution=$1654\text{pixels}$
    • Vertical resolution$=2338\text{pixels}$

• So the answer is that you need a  1654 × 2338 pixels.

Problem 42 :

• Here is it converted so it stays the same

• Width = $8.27\text{inches}$
• Height =11.69 inches

• Now we calculate the resolution

                  Horizontal resolution $=2481\text{pixels}$

                  Vertical resolution=3507pixels

• So the solution is that it needs 2481 × 3507 pixels.
