Perimeter of a square = 4 * side
P = 4 * (2x +1)
P = 8x + 4
Yes

If the rectangle has a width of x inches, and a length of x + 16 inches, then its perimeter equals to 2x + 2x + 32 or 4x + 32. If x = 14, then x + 16 = 30. So the perimeter of rectangle becomes 2(14) + 2(30) = 28 + 60 = 88 inches.
2(3x + 25) 6x + 50
