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.
A. 13x + 2
B. 13x + 1
C. 9x + 1
D. 9x + 2
The perimeter of a trapezoid is the sum of all its sides.
Perimeter = 2x + 4x + 1 + 3x + 4x + 1
Simplifying this expression:
Perimeter = 13x + 2
Therefore, the answer is A. 13x + 2.
