Answer 2

Answer:

Total cost of fencing = 2000  

Cost of fencing per meter = 25  

Total length of fencing = 2000/25 = 80 m  

Perimeter of rectangular field is 80 m  

Length of the rectangular field = 24 m

Perimeter of the rectangle:

⇒  2(l + b) = 80  

⇒  2(24 + b) = 80  

⇒ 24 + b = 80/2

           = 40  

⇒ b = 40 - 24  

⇒ b = 16

Therefore the breadth of rectangular field is 16 m.
