A farmer had a rectangular plot measuring 500 m by 100 m. If he fences the plot 4 times with barbed wire, what should be the length of the wire?
4800 m
Given: Length of the plot = 500 m
Breadth of the plot = 100 m
The farmer fences the rectangular plot four times.
⇒ Length of the wire = 4 × Perimeter of the rectangular plot
= 4 × 2 (length + breadth)
= 4 × 2 (500 + 100)
= 4 × 2 (600)
= 4800 m
Therefore, the length of the wire should be 4800 m.
