Question

Find the length of a barbed wire required to fence a square field of side of $183m$, when the wire goes $4$times round the field.

Answer 1

STEP1: Finding perimeter of a square field

Side of the square field$=183m$

Perimeter of a square$=4\times sideofasquare$

Perimeter of the square field$=4\times 183$

$=732m$

STEP2: Finding the length of a barbed wire required for fencing

Length of a barbed wire which goes $4$times round the filed$$\begin{gathered} =4\times perimeterofasquarefiled \\ =4\times 732 \\ =2928m \end{gathered}$$

Therefore, the length of a wired required for fencing a square field is $2928m$
