a) the area of a rectangle b) $\left(s + 5\right) \times \left(x + 4\right)$ = area
c) ${s}^{2}$ is the area of the square. not a polynomial
d${s}^{2} + 9 s + 20$ is the polynomial for the area of rectangle.

#### Explanation:

A polynomial must have three or more terms. ${s}^{2}$ the area of the square has only one term so is not a polynomial.
The area of the rectangle is a polynomial found by multiplying the two binomials (s + 5) and ( s + 4)
