    If the perimeter of a rectangular field is 120 feet and the length of one side is 25 feet, how wide must the field be?

    The perimeter of a rectangle P, is denoted as:
    P = 2l + 2w

    We're given l = 25, and P = 120, so we have
    2(25) + 2w = 120

    Simplify:
    2w + 50 = 120

    Typing this equation into our search engine, we get:
    w = 35
