# Two girls walk home from school. Starting from school Susan walks north 2 blocks and then west 8 blocks, while Cindy walks east 3 blocks and then south 1 block. Approximately how many blocks apart are the girls' homes?

Approximately $11.4$ blocks (assuming the blocks are perfectly square.
Cindy's house is $8 + 3 = 11$ blocks further East than Susan's.
Cindy's house is $2 + 1 = 3$ blocks further South than Susan's
$\textcolor{w h i t e}{\text{XXX}} \sqrt{{11}^{2} + {3}^{2}} = \sqrt{130} \approx 11.40175$ blocks apart.
