Question

What is the perimeter of a square with side 5cm?​

Answer 1

Answer:

20 cm

Step-by-step explanation:

As all the sides of a square are equal,

Perimeter of a square is four times its one side.

As side of the square is 5  cm,

Its perimeter is  5  ×  4  =  20  cm

Answer 2

$\boxed{\huge{\bf{\star{Correct\:question \:-:}}}}$

$\large{\sf{What\: is\: the \:perimeter\: of\: a\: square\: with\: side\: 5\:cm?}}$

$\boxed{\huge{\bf{\star{Answer\:-:}}}}$

$\sf{\rightarrow {Perimeter\:of\:square\:=20 cm}}$

$\large{\sf{Explanation-:}}$

$\large{\sf{Given,}}$

$\sf{\rightarrow {The\:Length \:of\:side\:of\:a\:square \:is\:5cm.}}$

$\large{\sf{To\:Find,}}$

$\sf{\rightarrow {The\:Perimeter \:of\:a\:square.}}$

$\large{\sf{Solution,}}$

$\sf{\star{The\:Perimeter \:of\:a\:square.}}$

$\sf{\rightarrow {Perimeter\:=\:4 \times Side \:of\:a\:square}}$

$\sf {Here}\\\\{\sf{Side\:of\:a\:square=\:5cm}}$

$\sf {Now,}\\\\{\sf{\rightarrow {P=\:5 \times 4}}}\\\\{\sf{P= \:20cm}}$

$\sf {Hence,}\\\\{\sf{\rightarrow {Perimeter\:of\:square\:=20 cm}}}$

$\large{\sf{Let's\:Explore.............}}$

$\sf{\star{The\:Perimeter \:of\:a\:square.}}$

$\sf{\rightarrow {Perimeter\:=\:4 \times Side \:of\:a\:square}}$

$\sf{\star{The\:Area \:of\:a\:square.}}$

$\sf{\rightarrow {Are\:=\:Side\:of\:a\:square \times Side \:of\:a\:square}}$

$\sf{\star{The\:Side \:of\:a\:square.}}$

$\sf{\rightarrow {Side\:=\frac {Perimeter \:of\:a\:square}{4}}}$

$\sf{\star{The\:Diagonal \:of\:a\:square.}}$

$\sf{\rightarrow {Diagonal \:=\: \sqrt 2 \times Side \:of\:a\:square}}$
