The dimensions 4.5 cm (height) x 3.5 cm (width) are equivalent to 354 x 276 pixels at 200 dpi.
Explanation:
Given, the dimensions are 4.5 cm x 3.5 cm
Since, 1 inch = 2.54 centimeters
(4.5/2.54) = 1.77
(3.5/2.54) = 1.38
4.5 cm x 3.5 cm is equivalent to 1.77 in x 1.38 inch
According to, the given dpi (dots per inch or pixels per inch) is 200 which means there are 200 dots or pixels in 1 inch.
Therefore, the pixel dimensions can be calculated as follows: 1.77 x 200 x 1.38 x 200 pixels = 354 x 276 pixels.
