Detailed Solution

The cost of fencing a rectangular field at ₹ 30 per meter is ₹ 2400. If the length of the field is 24 m, then its breadth is 16 m.
Given the cost of fencing a rectangular field at ₹ 30 per meter is ₹ 2400.
Perimeter of field is,
= cost of fencing rectangular field cost of fencing per meter  
= 2400 30  
= 80m
Let breadth be x.
Now, the perimeter of the rectangle = 2(Length + Breadth).
80 = 2(24 + x)
48 + 2x =80
2x = (80-48)
2x = 32
x= 32 2  
x = 16 m
The breadth of the rectangular field is 16 m.
