  1. Answer:

    side= 2.25m

    fencing cost= 67.5

    leveling cost= 15.18

    Step-by-step explanation:

    Side

    36m = roam around field 4 times

    36m = (perimeter) *4

    36/4  = (perimeter)

    9 = (perimeter)

    9 = 4*side

    side = 9/4 = 2.25m

    Fencing

    Fencing thrice = (perimeter) *3

    = 9 * 3 = 27m

    1m = 2.5 , 27m=?

    = 27*2.5 = 67.5

    cost = 67.5

    Leveling

    Area = 9/4 * 9/4

    = 81/16 [tex]m^{2}[/tex]

    cost = 81/16 *3

    = 243/16

    = 15.18
