The perimeter of an object is all of its sides added up. So it gives you the length and widths of the shape. A. X + 4 + X + X + 4 + X = 34. But we can simply that even further. To 4X + 8 = 34
B. So solve that you would first Subtract 8 from each side. You then get 4x = 26 X = 13/2 13/2 is your answer. You can simplify this to 7.5 but ask your teacher if you can leave it as 13/2 because it will save you a lot of time on a test.
