Question

Find the length of the side of a
square whose area is 440 m²​

Answer 1

Step-by-step explanation:

area of the square = 440

a^2=440

a=root under 440 meter

Answer 2

⠀⠀${\huge{\underbrace{\rm{Correct\:Question}}}}$

Find the length of the side of a square whose area is 441 m²

⠀⠀${\huge{\underbrace{\rm{Required\:Answer}}}}$

⠀⠀

Given:

⠀⠀

• Area of the square is 441 m²

⠀⠀

To find:

⠀⠀

Find the length of the side of a

square

⠀⠀

Solution:

⠀⠀

Let the length of the side of the square be ' x ' m

We know that,

$\boxed{\bf{\red{Area\:of\:square=(side)^{2}}}}$

According to the question,

⠀⠀

$\sf{\implies x^{2}=441}$

⠀⠀

$\sf{\implies x=\sqrt{441}}$

⠀⠀

$\sf{\implies x=21}$

⠀⠀

Therefore,

⠀⠀

$\dashrightarrow\:\:\underline{\boxed{\sf the\:length\:of\:the\:side\:of\:the\:square\:is\:21\:m}}$

● $\sf{Area\:of\:square=(side)^{2}}$

⠀⠀

We know that all sides of the square are equal.

Let the side of square be 'a'

Since all sides are equal width and height of the square will be 'a'

Area of square = Width × Height

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= a × a

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= a²

⠀⠀

● $\sf{Perimeter\:of\:square=4×side}$

⠀⠀

if side of a square is 'a'

then perimeter of square is = a+a+a+a=4a
