Four rounds of wire fence have to be put around a field. If the field is 60 m long and 40 m wide, how much wire will be needed? |

Answer» Perimeter of rectangular field = 2 x length + 2 x breadth = 2 x 60 + 2 x 40 = 120 + 80 = 200 m Hence, wire required for 4 rounds = 200 x 4 = 800 m ∴ Wire required for 4 rounds = 800 m |
