The dimensions 3.5 cm (width) x 1.5 cm (height) are equivalent to 276 x 118 pixels at 200 dpi.
Explanation:
The dimensions given are 3.5 cm (width) x 1.5 cm (height)
Since, 1 inch is equal to 2.54 centimeters
(3.5/2.54) = 1.38
(1.5/2.54) = 0.59
4.5 cm x 3.5 cm is equivalent to 1.38 in x 0.59 inch
According to, the given dpi (dots per inch or pixels per inch) is 200, there are 200 dots or pixels in an inch.
Therefore, the pixel dimensions can be calculated as follows: 1.38 x 200 x 0.59 x 200 pixels = 276 x 118 pixels.
