secret66 · Answer

Pentagon=five sides. 
19.9 + 24.8 + 30 + 49.2 = 123.9 cm 
156 - 123.9 = 32.1 cm (final answer)

a_clan · Answer

perimeter of the regular hexagon= 26 * 6
perimeter of the irregular pentagon= 19.9 + 24.8 + 30 + 49.2 + x
Since both the perimeter have to be equal, hence
26 * 6 = 19.9 + 24.8 + 30 + 49.2 + x
