    Hi there! The answer is B.

    You have enough wallpaper to cover 240 square feet. If your walls are 8 feet high, what wall length can you paper?

    First write down our dа ta:

    A = 240 square feet

    l = 8 feet

    Now we can fill in the formula

    240 = 8 * w

    Switch sides.

    8 * w = 240

    Divide both sides by 8.

    w = 240 / 8 = 30

    Therefore the answer is B.

    Wall length of 30 feet
