Fernando, an interior decorator, is designing an entryway for a client's new home. The entryway will include a set of double doors and hardwood moulding. The moulding will be an equal width around the sides and top of the double doors, which will be $60$ inches wide and $80$ inches tall. The total area of the double doors and moulding in square inches can be modeled by the expression $(2x + 60)(x + 80)$, where $x$ is the width of the moulding in inches. This expression can also be written in the form $2x^2 + 220x + 4,800$. What does the quantity $2x^2 + 220x$ represent in the expression?$\newline$(A)the perimeter around the outside of the double doors and moulding in inches$\newline$(B)the area of the double doors in square inches$\newline$(C)the height of the double doors and moulding together in inches$\newline$(D)the area of the moulding in square inches
