3.5 cm x 1.5 cm at 200 dpi is equivalent to 276 x 118 pixels.
Explanation:
The given dimensions are 3.5 cm x 1.5 cm
Since, 1 inch is equal to 2.54 cm
(3.5/2.54)=1.38
(2.5/2.54)=0.984
4.5 cm x 3.5 cm is equal to 1.38 in x 0.59 in
Now, the given dpi (dots per inch or pixels per inches) is 200 that means there are 200 dots or pixels in 1 inch
Hence, the dimensions in pixels will be 1.38 x 200 x 0.984 x 200 pixels =276 x 197 pixels.
