I saw the image that should have accompanied this problem.
V (-3,-2)
W( 4, 6)
I studied the graph and I can form a right triangle with VW as the hypotenuse.
long leg = 8 units ; short leg = 7 units
Pythagorean theorem
a² + b² = c²
8² + 7² = c²
64 + 49 = c²
113 = c²
√113 = √c²
10.63 = c
the length of stack VW with bar on top is 10.63
