    10 meters.

    68-24-24/2=10

    Perimeter formula for a rectangle:

    2w+2L=p, where:

    w = width

    L = length

    a = perimeter.

    We are giving the length: 24. We need to find the width.

    However, don't panic, since we are also given the perimeter: 68.

    Just plug in numbers and leave "w" as the only variable.

    2w + 2 (24) = 68

    Simplify.

    2w+48=68

    2w=20

    w=10

    The patio is 10 meters wide.
