    area of the rectangular yard = 72 * 42 = 3024 ft²

    area bounded by the fence = 34 * 64 = 2176 ft²

    area of walk = 848 ft²

    Step-by-step explanation:

    The rectangular yard has a dimension of 42 ft by 72 ft.

    The area of the rectangular yard = Length * width

    L = 72 ft

    W = 42 ft

    area of the rectangular yard = 72 * 42 = 3024 ft²

    The rectangular yard is surrounded by a fence and a walkway is also inside the fence. This means reduce 4 ft for all sides of the rectangular yard to get the area of the walkway. This means reduce 8 ft to the length and width of the rectangular yard.

    Length of fence = 72 - 8 = 64 ft

    width of fence = 42 - 8 = 34 ft

    area inside the walkway = 64 * 34 = 2176 ft²

    area of walk = 3024 - 2176

    area of walk = 848 ft²
