​

Answer 1

Answer:

Total cost of cultivating the rectangular field at Rs.15 per metre square is RS. 18330.

=>Area of the rectangular field=18330/15=1222 sq metres.

It's breadth is 26 m.

=>Length=Area/breadth=1222/26=47 m

It's Perimeter=2(47+26) m=146 m

Cost of fencing the field =perimeter×20=Rs.(146×20)=Rs.2920
