Let there be an equilateral triangle with a side length of \( 16\,\mathrm{cm} \). Connecting the centres of its sides with line segments we form another equilateral triangle. If we add three more triangles using the same procedure, what is the sum of their perimeters?
\( 93\,\mathrm{cm} \)
\( 72\,\mathrm{cm} \)
\( 144\,\mathrm{cm} \)
\( 31\,\mathrm{cm} \)
\( 90\,\mathrm{cm} \)
