In an isosceles triangle, where the perimeter is 22 cm and one side is 6 cm, the two equal sides must each measure 8 cm because the sum of the two equal sides plus the third side (6 cm) must equal the total perimeter (22 cm), i.e., \(x + x + 6 = 22\) simplifying to \(2x = 16\), resulting in \(x = 8\).
