Question

The cost of fencing a rectangular field at Rs30 per metre is Rs2400. If the length of the field is 24m,then the breadth is *
​

Answer 1

Answer:

Total cost of fencing = Rupees 2400

Rate = Rupees 30 per m

Perimeter of the rectangular field =2(l+b)=2400/30  =80 m

Hence, length + breadth =80/2  =40 m

Length of field =24 m

Breadth of field =40−24  =16 m
