    Answer:

    Step-by-step explanation:

    The length of a living room is 12 feet and its width is 10 1/2 feet. The length of the room is being expanded by x feet. Assuming the increase in length is only on one side of the room, it means that the new length would be (12 + x) feet

    The formula for determining the area of a rectangle is expressed as

    Area = length × width

    Therefore, an expression to represent the new area of the living room in square feet would be

    10.5(12 + x)

    New area = (126 + 10.5x) square feet
