Question

The side of the square field is 65 m . What is the length of the fence required all around it ?

Answer 1

Hint: It is given that the side of the square field is 65 m and we need to find the length of the fence and to find the length of the fence it is enough to find the perimeter of the square as the fence covers only the boundary of the field . the perimeter of the square is given by the formula $Perimeter=4\ast sideunits$

Complete step-by-step answer:
We are given that the side of the square field is 65 m
We know that in a square all sides are equal

We are asked to find the length of the fence around it
We know that the fence is made around the boundary and not inside .
Hence its enough to find the perimeter of the square
We know that the perimeter of the square is given by the formula
$\Rightarrow Perimeter=4\ast sideunits$
Hence here the side is 65 m
Therefore ,
$\begin{array}{c}\Rightarrow Perimeter=4\ast 65m\\ \Rightarrow Perimeter=260m\end{array}$
Therefore the length of the fence required is 260 m.

Note: Many students get confused whether to find the area or perimeter .
Since the fence covers only the boundary it's enough to find the perimeter here and we need to find the area only when the inner part of the square is included
Students may tend to forget the formula so in the case of perimeter the sum of the all the sides gives the required perimeter
