Exercise 41 and 42

 Problem 41:

1. Convert the paper size to inches:

   • 1 inch = 25.4 mm
   • Width: $210 \, \text{mm} \div 25.4 = 8.27 \, \text{inches}$
   • Height: $297 \, \text{mm} \div 25.4 = 11.69 \, \text{inches}$

2. Multiply the dimensions by the required DPI (200 dpi):

   • Width resolution: $8.27 \, \text{inches} \times 200 \, \text{dpi} = 1654 \, \text{pixels}$
   • Height resolution: $11.69 \, \text{inches} \times 200 \, \text{dpi} = 2338 \, \text{pixels}$

Solution: 1654 x 2338 pixels

Problem 42

1. Convert the paper size to inches:

   • Width: $210 \, \text{mm} \div 25.4 = 8.27 \, \text{inches}$
   • Height: $297 \, \text{mm} \div 25.4 = 11.69 \, \text{inches}$

2. Multiply the dimensions by the required DPI (300 dpi):

   • Width resolution: $8.27 \, \text{inches} \times 300 \, \text{dpi} = 2481 \, \text{pixels}$
   • Height resolution: $11.69 \, \text{inches} \times 300 \, \text{dpi} = 3507 \, \text{pixels}$

Soulution: 2481 x 3507 pixels
