Well, since readability obviously isn't an issue, just change the
variable names to w and h and you've save 9 characters before you even
get started. OTOH, you could use printf and wind up with a slightly
easier to read, but still 7 character longer than desired, line of code.

printf "Size: %dx%d.\n",$height,$width;
