    the newer moat is 169 cm longer than the older one

    Step-by-step explanation:

    in order to find the difference in length of the two castles, we will first find the perimeters of the two castles then calculate the difference in the perimeters:

    old castle:

    dimension = 484cm by 386cm

    perimeter = 484 + 386 = 870 cm

    new castle:

    dimension = 725cm by 314cm

    perimeter = 725 + 314 = 1039 cm

    difference = 1039 - 870 = 169 cm

    The total length of the moats used is equals to the perimeter of the sand castles, therefore, the newer moat is 169 cm longer than the older one.
