Answer:
6x
Step-by-step explanation:
okay, so you have that one side is x feet. you have six sides. Perimeter is the distance of all the sides added together. so, if each side is x, and you have 6 sides, you can multiply x times 6 because each side is the same (it is the same as adding each side individually, but it is faster). so, you would have that the perimeter is 6x. Because we don't have any more information, this would be your answer.
