Step-by-step explanation:
length of walkway = 20 + 2x
width of walkway = 15 + 2x
A(x) = (20 + 2x)(15 + 2x)
A(x) = 300 + 30x + 40x + 4x2
A(x) = 300 + 70x + 4x2

Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
Knowing this, we should start by doing the equations <em>within </em>each parentheses.

So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:

20 is the answer.
