Let \( ABCD \) be a trapezium with the base $AB$ of \( 8\,\mathrm{cm} \). The remaining sides have the same length. The measure of \( \measuredangle DAB \) is \( 60^{\circ} \). Calculate the perimeter of the trapezium.
\( 20\,\mathrm{cm} \)
\( 4\,\mathrm{cm} \)
\( 14\,\mathrm{cm} \)
\( 24\,\mathrm{cm} \)
