    The correct answer is 11 ft.

    Explanation:

    The diagonals of a parallelogram bisect each other. This means that the portion marked x+4 is the same length as the portion marked 2x-7; this gives us the equation x+4=2x-7.

    Subtract x from each side:

    x+4-x=2x-7-x

    4=x-7.

    Add 7 to both sides:

    4+7=x-7+7

    so x=11
