A $2$D image was been spatially digitized with a $7-$bit processor. If the area imaged is $\backslash (23\backslash$mathrm$\{$~cm$\}\backslash$times $23\backslash )$ cm $,$ and pixels are square elements, what is the pixel size? Report answer in units of $\backslash (\backslash$mathrm$\{$mm$\}\backslash$times $\backslash$mathrm$\{$mm$\}\backslash ).$ Hint: Pixel size$=$ length of the image$/$ number of pixels
