Chumki, Jhumri, and Imran need wire to make a fence.
- Who will need the longest wire for fencing?
उत्तर
- Perimeter of Chumki’s land
= 9 + 2 + 3 + 2 + 6 + 4
= 26 m - Perimeter of Jhumri’s land
= 6 + 3 + 2 + 3 + 4 + 6
= 24 m - Perimeter of Imran’s land
= 8 + 5 + 3 + 2 + 5 + 3
= 26 m
It is clear that Chumki and Imran need the longest and equal wires to fence their lands.
