h: x = [-2, -1, -1] + r·([0, 3, 1] - [-2, -1, -1]) = [-2, -1, -1] + r·[2, 4, 2]
k: x = [2, 3, 3] + r·[2, 4, 2]
Abstand von B zu h
d(B, h) = ABS(([2, -1, 3] - [-2, -1, -1]) ⨯ [2, 4, 2]) / ABS([2, 4, 2]) = 8/3·√3
Abstand von B zu k
d(B, k) = ABS(([2, -1, 3] - [2, 3, 3]) ⨯ [2, 4, 2]) / ABS([2, 4, 2]) = 4/3·√3
A1 : (A1 + A2) = (4/3·√3)^2 : (8/3·√3)^2 = 1:4
A1:A2 = 1:3
