Question

Ranbir bought a rectangular field of area 24000 square metres and width 120 m. He wants to fence it with two rounds of wire. Find the length of wire that will be required to fence the field.

Answer 1

640 metres

Explanation:

Area of a rectangular field = 24000 square metres

Width of a rectangular field = 120 metre

Also,

Area of a rectangular field = Length × Breadth

24000 = Length × 120

Length =
`(24000)/(120)=200` metre

Length of wire required to fence the field = Perimeter of the rectangular field

= 2 (length + width)

= 2 (200 + 120)

= 2 (320)

= 640 metres
