<h2>Answer:</h2>
Part A
<u>The area is 20x5+16x4−26x3+22x2+32x−24 sqaure units</u>
Part B
<u>Yes the answer is polynomial</u>
Part C
<u>The degree is 5</u>
<h2>Step-by-step explanation:</h2><h3>Part A</h3>The solution is given in the attached figure
<h3>Part B</h3>In mathematics, a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. So the answer is a polynomial in our case.
<h3>Part C</h3>The degree of a polynomial is the highest degree of its individual terms with non-zero coefficients. The degree of an expression is the sum of the exponents of the variables that appear in the polynomial, and thus is a non-negative integer. In our case the degree of the polynomial is 5.
