Question 1170185: Hi, I was wondering if someone could show me the steps and the answer.
My teacher wants something like let x=
The length of each side of a square is 6 feet more than the length of a side of a regular octagon. The perimeter of the square is equal to the perimeter of the octagon. Find the length of a side of the square and the length of a side of the octagon.

Let x = the side length of the octagon
Then x+6 is the length of each side of the square
Since the perimeters are equal, we have:
4(x+6) = 8x
8x - 4x = 24 -> x = 6
Thus, the length of the sides of the square is 12
