#### Hence, the length of the square field is 245 m.The square has four sides, so the number of boundaries of the field is 4.The distance s covered by the man = 245 m ×× 4 = 980 m = 0.98 kmIf the velocity v is 18 km/hr, the required time t can be calculated using the following formula:t= s/v #### Answer 10: First, we have to find the area of the square lawn, which the total cost divided by the cost of levelling and turfing per square metre: The length of one side of the square is equal to the square root of the area. We will use the long division method to find it as shown below: Length of one side of the square = 73 m
The circumference of the square is 73 ×× 4 = 292 m
Total cost of fencing the lawn at Rs. 5 per metre = 292 ×× 5 = Rs. 1460
