Answer 1

Answer:

The length of barbed wire required to build a fence around it = 600 m

Step-by-step explanation:

Length = 120 m

Breadth = 180 m

Perimeter = 2(L +  B)

= 2(120+180)

=2(300)

= 600 m

Answer 2

Step-by-step explanation:

total perimeter of field is

$2 \times 120 + 2 \times 180$

$240 + 360$
