The perimeter of a polygon is simply the sum of the lengths of its sides. There is no polynomial that expresses that for all polygons, but the perimeter of a rectangle is P=2(L+H) where P is the perimeter, L is the length, and H is the height.

Ex: Write the polynomial in standard form that represents the perimeter of a rectangle with a length of 2x−5 and width of 5x+1.
Ans: The formula for the perimeter L+L+W+W. So sub 2x-5 for L and 5x+1 for W. The new equation is 2x-5+2x-5+5x+1+5x+1.
That already is a polynomial in standard form.

You can evaluate a polynomial, you can factorise a polynomial, you can solve a polynomial equation. But a polynomial is not a specific question so it cannot be answered.
