Total walk to the south=9+3=12  Total walk to the east=2+7=9  Distance from initial position       =(√(12^2 +9^2 )) =15 blocks
$$\mathcal{T}{otal}\:{walk}\:{to}\:{the}\:{south}=\mathrm{9}+\mathrm{3}=\mathrm{12} \\ $$$$\mathcal{T}{otal}\:{walk}\:{to}\:{the}\:{east}=\mathrm{2}+\mathrm{7}=\mathrm{9} \\ $$$${Distance}\:{from}\:{initial}\:{position} \\ $$$$\:\:\:\:\:=\sqrt{\mathrm{12}^{\mathrm{2}} +\mathrm{9}^{\mathrm{2}} }\:=\mathrm{15}\:\mathrm{blocks} \\ $$
