    Answer:

    Area = 25km² in a century.

    Explanation:

    Given

    Spread Rate = 5m/century

    Length of rift = 5000km

    Convert to metres

    Length of rift = 5000 * 1000m

    Length of rift = 5,000,000m

    In one century, the additional area to Atlantis = (Rift Length) * (Spread rate) * 1 century

    Atea = 5,000,000 m * 5m/century * 1 century

    Area = 25,000,000m² in a century

    —– Convert to km²

    Area = 25,000,000km² * 1m²/1,000,000km²

    Area = 25km² in a century.

    Hence, the total area of new ocean floor created in the Atlantic each century is 25km²
