    The ratio of the media room tv's width to height is 8ft to 4.5ft or 8/4.5

    since the ratio of the living room tv's width to height is the same, the ratio would be

    x/27 = 8/4.5

    with x being the living room tv's width. Solve for x

    x = (8/4.5) (27)

    = 48

    The width of the living room tv is 48 inches
