Start with:
d+=+sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2%2B%28y%5B2%5D-y%5B1%5D%29%5E2%29 where: d = distance, and the x- and y-coordinates of the two given points 1 and 2 are the (x%5B1%5D,y%5B1%5D) and (x%5B2%5D,y%5B2%5D) respectively.
Make the appropriate substitutions.
d+=+sqrt%28%2812-8%29%5E2%2B%2811-8%29%5E2%29
d+=+sqrt%284%5E2%2B3%5E2%29
d+=+sqrt%2816%2B9%29
d+=+sqrt%2825%29
highlight%28d+=+5%29
