    Perimeter = 84

    Area = 360

    Step-by-step explanation:

    We know that this field has portions split up by 7. The length is 5/7 of that, and the width is 2/7.

    We know that the length is 30yd. 30/42 is the equivalent of 5/7. That means that 12/42 is the equivalent of 2/7.

    Thus, the width of the field is equal to 12.

    To find the perimeter we will add all sides. 30 + 30 + 12 + 12 = 84

    We will multiply them to find area. 30 * 12 = 360
