Question

Length and breadth of a rectangular field are 25 m and 15 m respectively. Find the barbed wire required to fence the field.​

Answer 1

80 m

perimeter of the rectangle(p) = wire required to fence the field

perimeter = 2(length × breadth)

= 2(l×b)

p = 2 (25×15)

p = 2 (40)

perimeter = 80 m

barbed wire required to fence the field= 80 m
