please always answer my question with statement so then I can mark you brainlist​

Answer 1

AnswEr :

• The area of a square = 9 m².

⠀

Explanation :

We are given with the side of a square, that is,

• Side of square, a = 3 m.

We have to find out the area of a square.

Diagram :

$\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(4,0){2}{\line(0,1){4}}\multiput(0,0)(0,4){2}{\line(1,0){4}}\put(-0.5,-0.5){\bf D}\put(-0.5,4.2){\bf A}\put(4.2,-0.5){\bf C}\put(4.2,4.2){\bf B}\put(1.5,-0.6){\bf\large 3 cm}\put(4.4,2){\bf\large 3 cm}\end{picture}$

⠀

As we are given with the side of square.

We know that, if we are given with the side of square we have the formula, that is,

⠀

⠀

→ Area of square = a²

⠀

⠀

Substituting the given values in the formula :

⠀

$\sf{:\implies Area_{(square)} = {3}^{2} }$

⠀

$\sf{:\implies Area_{(square)} = 3 \times 3}$

⠀

$\sf{:\implies \boxed{ \pink{ \frak{Area_{(square)} = 9}}}}$

⠀

Hence, the area of a square is 9 m².
