Question

A rectangular piece of land measures 900 metre and 400 metre. Each side is to be fenced with five rows of wires, then the total length of the wire needed is?

Answer 1

Length of field = 900 m

Width of field = 400 m


Perimeter = 2 ( Length + Width)

= 2 ( 900 + 400)

= 2 × 1300

= 2600 m

Length of wire Required = 5 × Perimeter of field

= 5 × 2600 m

= 13000 m

Answer 2

Perimeter of piece =2(900+400)

Perimeter of piece =2×1300


Perimeter of piece =2600 m

Lenght of wires to be fenced = 5×2600


Total Lenght of wires to be fenced = 13000m




I hope this will help you
