Answer:
length of field:15
breadth of field:16
perimeter of field:2×(l+b)
=2×(15+16)
=2×31
=62
so,the perimeter of field is 62
total no. of round =4
rope required=62×4=248

L=15
B=16
Area of regular field=L×B
=15×16
=240
Area of regular field = 240
1 round =240
4round= x
240×4= 960
4rounds=960
Total length of the rope he must used =960
