Write the perimeter of the figure as a polynomial. Simplify.
A trapezoid is shown. The top side is labeled 2 x. The right side is labeled 4 x plus 1. The bottom side is labeled 3 x. The left side is labeled 4 x plus 1.

13x + 2
13 x + 2
13x + 1
13 x + 1
9x + 1
9 x + 1
9x + 2
Perimeter = sum of all sides
Perimeter = 2x + 4x + 1 + 3x + 4x + 1
Perimeter = 9x + 2
Therefore, the polynomial perimeter of the trapezoid is 9x + 2.
