Here are two methods:
a = {{1, 2, 3}, {3, 4, 5}, {5, 6, 7}}
b = {{11, 12}, {13, 14}, {15, 16}}
Transpose[Join @@ Transpose /@ {a, b}]
{{1, 2, 3, 11, 12},
{3, 4, 5, 13, 14},
{5, 6, 7, 15, 16}}
Needs["LinearAlgebra`MatrixManipulation`"]
BlockMatrix[{{a, b}}]
{{1, 2, 3, 11, 12},
{3, 4, 5, 13, 14},
{5, 6, 7, 15, 16}}
