The question is:
Which is the shorter distance?
AR or BR ?
---------
AR=
+sqrt%28+%28+5+-+1+%29%5E2+%2B+%28+3+-+1+%29%5E2+%29+
+sqrt%28+4%5E2+%2B+2%5E2+%29+
+sqrt%28+16+%2B+4+%29+
+sqrt%28+20+%29+
+2%2Asqrt%285%29+
-----------
BR=
+sqrt%28+%28+1+-+1+%29%5E2+%2B+%28+5+-+1+%29%5E2+%29+
+sqrt%28+0%5E2+%2B+4%5E2+%29+
+sqrt%28+0+%2B+16+%29+
+4+
B is closer to R
The difference is
