    Answer:

    5 by 10

    Step-by-step explanation:

    We know that the equation of a perimeter of a recangle is 2(l)+2(w), l being length and w being width. We know that l=2w. So the perimeter of this room would be:

    2(2w)+2(w)=30

    4w+2w=30

    6w=30

    w=5

    l=2w

    l=10

    the dimensions are 5 by ten
