Question

Find the length of the side of a square whose area is 441msq.

Answer 1

Answer:.

Given,

• Area of square = 441 m²

We need to find ,

• Side of square

___________________________

We know that

Area of square = Side²

Now , substituting area of square = 441 m²

→ 441 m² = Side²

→ Side = √441

→ Side = 21 m

Hence , area of square = 21 m

★ More information :-

Area of square = side²

Perimeter of square = 4(side)

Area of rectangle = l × b

Perimeter of rectangle = 2(l + b)

Area of triangle = 1/2 × base × height

Answer 2

$\bf{\underline{\underline{\bigstar\bigstar\: Solution :}}}$

$\:\:$

$\footnotesize{Area \: of \: square = {441m}^{2}}$

$\footnotesize{\implies {side}^{2} = {441m}^{2}}$

$\footnotesize{\implies side = \sqrt{{441m}^{2}}}$

$\footnotesize{\implies side = \sqrt{21m \times 21m}}$

$\footnotesize{\implies side = 21m}$

$\:\:$

$\bold{ side \: of \: square \: is \: 21m}$
