A1050 pixels wide by 600 pixels high
B150 pixels wide by 150 pixels high
C7 pixels wide by 4 pixels high
D450 pixels wide by 300 pixels high
Step-by-Step Solution

  1. Step 1: Calculate width in pixels

    Width = 7 inches * 150 dpi = 1050 pixels

  2. Step 2: Calculate height in pixels

    Height = 4 inches * 150 dpi = 600 pixels

  3. Final Answer:

    1050 pixels wide by 600 pixels high -> Option A

  4. Quick Check:

    Multiplying inches by dpi gives pixel dimensions [OK]
Quick Trick: Pixels = inches x dpi [OK]
Common Mistakes:
  • Using dpi as pixel count directly
  • Confusing inches with pixels
  • Multiplying dpi by wrong dimension
