Final answer:
To fence a rectangular field with a length of 1 km and breadth of 500 m, 3000 meters of wire are required.
Step-by-step explanation:
In this case, the length of the field is 1 km and the breadth is 500 m.
The formula to calculate the perimeter of a rectangle is P = 2(length + breadth).
Therefore, the perimeter of the rectangular field is P = 2(1 km + 500 m).
First, we need to convert the length and breadth to the same unit.
1 km is equal to 1000 m, so the perimeter can be calculated as P = 2(1000 m + 500 m).
Calculating this expression gives us P = 2(1500 m) = 3000 m.
Therefore, 3000 meters of wire are required to fence the rectangular field.
