Answer 1

Answer:

cost of levelling = 7,886.18 rupees

To complete 1 KM of round runner needs to take 5 rounds

Step-by-step explanation:

Area of ground = 60.5 m x 39.5 m = 2,389.75 sq. meter

cost of levelling = 2,389.75 x 3.30 = 7,886.18 rupees

-------------------

Now perimeter = 2(60.5 + 39.5) = 2 x 100 = 200 m

To complete 1 KM of round runner needs to take = 1000m/200m = 5
