    Answer:

    The circular field would require 1232 kg of fertilizer.

    Step-by-step explanation:

    0.5 m^{2} takes 1 kg of fertilizer.

    For a circular field of radius 14 m, its area = area of a circle

    area of a circle = \pi[tex]r^{2}[/tex]

    So that,

    Area of the circular field = \frac{22}{7} x 14 x 14

                               = 22 x 2 x 14

                               = 616

    Area of the field = 616 m^{2}

    Since, 0.5  m^{2} takes 1 kg of fertilizer. Let the kilograms of fertilizer required by the field be represented by x.

    Thus,

    x = \frac{616*1}{0.5}

      = 1232

    x = 1232 kg

    Therefore, the circular field would require 1232 kg of fertilizer.
