    Step-by-step explanation:

    Since the outdoor ice skating arena is in the shape of a circle, we would determine its area by applying the formula for determining the area of a circle which is expressed as

    Area = πr²

    Where

    π is a constant whose value is 3.14

    r represents the radius of the circle

    From the information given,

    Diameter = 42 feet

    Radius = diameter/2 = 42/2 = 21 feet

    Therefore,

    Area = 3.14 * 21² = 1384.74 square feet

    Rounding up to the nearest whole number, area of the outdoor ice skating arena would be 1385 square feet
