Question 2
Thirty-six points are arranged in a unit-square array as shown. Figure $ABCDE$ consists entirely of straight-line segments. If its perimeter is $x+y\sqrt5+z\sqrt{13}$ units, find $x+y+z$.
Here $x,y,z$ are the nonnegative integer coefficients after like radical terms have been collected.
**Input:** Choose one option.
