Question

area and perimetre of a square are equal in number.what is its side of length​

Answer 1

Answer:

side of length is 4

Step-by-step explanation:

let the side of a square be x

the,area of square is :x^2

and the perimeter of square is : 4x

given that x^2=4x

$x {}^{2} - 4x = 0$

$x(x - 4) = 0$

$x = 0 \: and \: x = 4$

if x= 0 then the square will not form

so the side of square is 4

Answer 2

Let,

• Side → l

A/Q,

$\mathtt{ \bold{Area \: \: of \: \: square = Perimeter \: \: of \: \: square }}$

$\bold{ \implies \: {l}^{2} = 4l}$

$\implies \bold{l \: = 4 \: unit}$

$\large{ \mathcal{ \bold{So, Side → 4 \: unit}}}$

♦ More to know:—

$\large \boxed{ \bold{† \: Area \: \: of \: \: Square → {(side)}^{2} }}$

$\large \boxed{ \bold{† \: Perimeter \: \: of \: \: Square → 4 \times side }}$
