Correct answer: Explanation: To find the perimeter of a regular hendecagon you must first know the number of sides in a hendecagon is 11. When you know the number of sides of a regular polygon to find the perimeter you must multiply the side length by the number of sides.
The answer is 72 (--> second choice).
I can prove it without calculator so you believe me:
![6\sqrt{8}\cdot3\sqrt{2}=6\cdot3\cdot\sqrt{8}\sqrt{2}=6\cdot3\cdo\sqrt{8\cdot2}=\\= 6\cdot3\cdot\sqrt{16}=6\cdot 3\cdot 4 = 72](https://tex.z-dn.net/?f=6%5Csqrt%7B8%7D%5Ccdot3%5Csqrt%7B2%7D%3D6%5Ccdot3%5Ccdot%5Csqrt%7B8%7D%5Csqrt%7B2%7D%3D6%5Ccdot3%5Ccdo%5Csqrt%7B8%5Ccdot2%7D%3D%5C%5C%3D%206%5Ccdot3%5Ccdot%5Csqrt%7B16%7D%3D6%5Ccdot%203%5Ccdot%204%20%3D%2072)
