Answer #1

Each pixel has rgb values. Hence each pixel takes 24 bits and the number of pixels in image are 1600*1200

And Hence the number of bits are 1600*1200*24 bits

Number of bytes are 200*1200*24

Number of kBytes are (200*1200*24)/1024=5625 KB

and number of MBytes are 5625/1024=5.49 MB

Hence the size of image is 5.49 MB

Do give a thumbs up

    We are given a color picture consisting of an m?n array AŒ1::m;1::n? of pixels, where each pixel specifies a triple of red, green, and blue (RGB) intensities. Sup- pose that we wish to compress this picture slightly. Specifically, we wish to remove one pixel from each of the m rows, so that the whole picture becomes one pixel narrower. To avoid disturbing visual effects, however, we require that the pixels removed in two adjacent rows be in the same or...

    AssignmentBitmap files map three 8-bit (1-byte) color channels per pixel. A pixel is a light-emitting "dot" on your screen. Whenever you buy a new monitor, you will see the pixel configuration by its width and height, such as 1920 x 1080 (1080p) or 3840x2160 (4K). This tells us that we have 1080 rows (height), and each row has 1920 (width) pixels.The bitmap file format is fairly straight forward where we tell the file what our width and height are. When...
