length of its side.​

Answer 1

Question :

The perimeter of a square garden is 120m. Find the length of its side.

Answer :

$\sf\pink{Given}$

• Perimeter is 120 m

$\sf\pink{To\:Find}$

• Length of side = ?

Explanation :

$\sf\purple{Perimeter \:of \:square = 4\times side}$

$\longrightarrow\sf{120 = 4\times side}$

$\longrightarrow\sf{\dfrac{120}{4}= side}$

$\longrightarrow\sf{30= side}$

• Therefore its side is 30 cm.

Answer 2

Answer:

Diagram of Square -

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(4,0){2}{\line(0,1){4}}\multiput(0,0)(0,4){2}{\line(1,0){4}}\put(-0.5,-0.5){\bf D}\put(-0.5,4.2){\bf A}\put(4.2,-0.5){\bf C}\put(4.2,4.2){\bf B}\put(1.5,-0.6){\bf\large {30\ m}}\put(4.4,2){\bf\large {30\ m}}\end{picture}$

Given -

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• $\red\implies\small\rm \pink{Perimeter \: of \: Square }=\purple{120}$

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

To Find -

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• $\red\implies\small \rm \pink{Lenght \: of \: side}=\purple{?}$

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Using Formula -

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• $\red\implies\small\rm{\pink{Side\:of\:square}}={\purple {\dfrac{Perimeter}{4} }}$

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution -

  ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\blue \implies \small\rm{ \pink{Side \: of \: Square }= \purple{\dfrac{120}{4}}} \\ \\ \blue \implies \rm {\pink{Side } = \purple{\cancel\frac{120}{4}}} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \blue\implies\rm{ \pink{Side}} = \purple{30 \: m}$

Therefore

The side of square is 30 m..
