The perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
<h3>
What is a perimeter?</h3>
A perimeter is a closed path that outlines either a two-dimensional shape or a one-dimensional length.
Given that the length is 3x+2 and the width is 2x-1. The perimeter of a rectangle is given below.



A polynomial function is a function that involves only positive integer exponents of a variable in an equation.
Hence we can conclude that the perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
