Question

the perimeter of a squareis 36 cm then it's sides are of dash cm​

Answer 1

Answer:

$perimeter \: \: \: \: 4a = 36 \\ a = \frac{36}{4} \\ = 9 \: cm$

Answer 2

Corrected Question :

• The perimeter of a square is 36 cm find its area.

A N S W E R :

• The area of the square is 81 cm²

Given :

• The perimeter of a square is 36 cm

To find :

• Find its area ?

$\large\star$ As we know that,

$\large\dag$ Formula Used :

• $\boxed{\bf{\therefore \: Area\: of\: sqaure\:=\:side \: \times \: side}}$

Solution :

:$\implies$${\sf{Perimeter \:of\: square\: = \:36\: cm}}$

$~~~$:$\implies$${\sf{Side\:=\; \dfrac{Perimeter}{4}}}$

$~~~~~~~$:$\implies$${\sf{Side\:=\; \dfrac{36}{4}}}$

$~~~~~~~~~~~$:$\implies$${\sf{Side\:=\; {\cancel{\dfrac{36}{4}}}}}$

$~~~~~~~~~~~~~~~$:$\implies$${\sf{Side\:=\; 9\:cm}}$

$~~~~~~~~~~~~~~~~~~~$:$\implies$${\sf{Side\:=\; 9 \: \times \: 9}}$

$~~~~~~~~~~~~~~~~~~~~~~~$:$\implies$${\underline{\boxed{\frak{\pink{Side\:=\;81\:cm^2}}}}}$★

Hence,

• ${\underline{\textsf{The\;area\:of\:the\: Square \:is\:\textbf{81\:cm²}.}}}$

$~~~~$$\qquad\quad\therefore{\underline{\textsf{\textbf{Hence, Verified!}}}}$
