    Answer: 50 yards by 25 yards

    Step-by-step explanation:

    rink is also a rectangle

    perimeter = 150 yards

    length = 2x

    width=x

    the perimeter of rink is:

    p=2 (length + width)

    150=2 (2x + x)

    150 = 2 (3x)

    150 = 6x

    x=150 / 6

    x=25

    so width is 25 yards and length is twice the width which is 2x

    length = 2 * 25

    length = 50 yards

    so the dimension is 50 yards by 25 yards
