Question

The length and breadth of a rectangular field is 230m and 180m, if 5 rounds of fencing wire was required, is the length of fencing wire.​

Answer 1

Answer:

fencing is done at the boundary i.e. perimeter of rectangular field

length of rope for 5 rounds of fencing =perimeter of rectangular field×5

perimeter=2(l+b)

=2(180+230)

=2×410

=820m

length of rope required=820×5

=4100m

Step-by-step explanation:

Answer 2

Answer:

4100m

Step-by-step explanation:

Fencing = Perimeter of the Rectangular Field

Perimeter of a rectangle = 2(l+b)

Perimter = 2(230+180)m

2 * 410 m

820m

Length required for 5 rounds = (820 * 5)m

4100m

Hence the length required is 4100m
