Solution;
Length Of Rectangular Park = 300 meter
Breadth Of Rectangular Park = 115 meter
Perimeter Of Park = 2 ( Length + Breadth )
= 2 (300 + 115)
= 2 (415)
= 830 meter
Length Of Wire Required = Perimeter Of Park
= 830 meter
Cost Of Fencing 1 meter wire = Rs 20
Cost Of Fencing 830meter wire=20×830
= Rs 16600 Answer....
