Answer:side= 2.25m

fencing cost= 67.5

leveling cost= 15.18

Step-by-step explanation:Side36m = roam around field 4 times

36m = (perimeter) *4

36/4 = (perimeter)

9 = (perimeter)

9 = 4*side

side = 9/4 = 2.25m

FencingFencing thrice = (perimeter) *3

= 9 * 3 = 27m

1m = 2.5 , 27m=?

= 27*2.5 = 67.5

cost = 67.5

LevelingArea = 9/4 * 9/4

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

cost = 81/16 *3

= 243/16

= 15.18
