Best answer

Length of the rectangular garden = 40 m 

Area of the rectangular garden = 1000 sq. m. 

∴ length × breadth = 1000 

∴ 40 × breadth = 1000 

∴ breadth = 1000/40

= 25 m 

Now, perimeter of the rectangular garden = 2 × (length + breadth) 

= 2 (40 + 25) 

= 2 × 65

 = 130 m 

Length of one round of fence = circumference of garden – width of the entrance 

= 130 – 4 

= 126 m 

∴ Total length of fencing = length of one round of wire × number of rounds 

= 126 × 3 

= 378 m 

∴ Total cost of fencing = Total length of fencing × cost per metre of fencing 

= 378 × 250 

= 94500 

∴ The cost of fencing the garden is Rs 94500
