I am working through this problem and I noticed that this problem is very advanced. The only two side lengths are 6x centimeters, and -3x + 18. Could anyone help for X

Well, we know that the lengths of a square are all equal. So 6x must be equal to -3x + 18.

6x = -3x + 18.

Add 3x to both sides to get:  9x = 18

Divide both sides by 9 to get x =2.

x =2.

And the perimeter would be 8 cm.
