Answer: P = 12x + 18

Step-by-step explanation: When you find the perimeter, you do length + length + width +width. Saying 2L + 2W = P is the same thing.

  • 2L = 2(4x +6)
  • 2W = 4x +6 (if the width is equal to half the length, twice the width is equal to the length).
  • P = 2L + 2W
  • P = 2(4x + 6) + 4x + 6 (substitute for L and W)
  • P = 8x + 12 + 4x + 6 (distribute)
  • P = 12x + 18 (combine like terms)
