Answer:

Area: 9cm²

Perimeter: 12 cm

Explanation:

Area is length x width

It's a square so length and width are the same

3 times 3 is 9

And to find the perimeter you just add the side lengths

Squares have 4 sides and the given side length is 3 so 3x4 OR 3+3+3+3 is how you get the perimeter.

  • Side of a Square = 3cm

\star \blue{\frak{To \: find :}}


\\ \\

  • Area of a Square

  • Perimeter of a Square

There are two parts in this question. In first part we have to find area and in second part we have to find perimeter of a Square.


\\ \\


\green{ \text{part \: 1}}


\\

To find Area of a Square :

we know:


\bigstar \boxed{ \tt{Area \: of \: a \: Square = }{ \tt{side}^(2) }}


\\

So :


\\


\dashrightarrow \sf{Area \: of \: a \: Square = }{ \sf{side}^(2) }


\\ \\


\dashrightarrow \sf{Area \: of \: a \: Square = }{ \sf{3}^(2) }


\\ \\


\dashrightarrow \sf{Area \: of \: a \: Square = }{ \sf3 * 3}


\\ \\


\dashrightarrow \sf{Area \: of \: a \: Square = }{ \sf9cm {}^(2) }


\\ \\


\therefore \underline \textsf{ \textbf{Area \: of \: a \: square \: = \red{9 {cm} }}} \red{ \bf^(2)}


\\ \\


\green{ \text{part \: 2}}


\\ \\

To find perimeter of square :


\\ \\


\bigstar \boxed{ \tt{Perimeter \: of \: a \: Square = }{ \tt4 * {side}}}


\\ \\

So:


\\ \\


\dashrightarrow \sf{Perimeter \: of \: a \: Square = }{ \sf4 * side} \\


\\ \\


\dashrightarrow \sf{Perimeter \: of \: a \: Square = }{ \sf4 * 3} \\


\\ \\


\dashrightarrow \sf{Perimeter \: of \: a \: Square = }{ \sf12cm} \\


\\ \\


\therefore \underline{ \textsf{ \textbf{perimeter \: of \: a \: square \: = \red{12cm}}}}
