Answer 1

Answer:

Question :-

• The area of a square park is 121 m². Find its side.

Given :-

• The area of a square park is 121 m².

To Find :-

• What is the side of a square park.

Formula Used :-

$\clubsuit$ Area Of Square Formula :

$\bigstar \: \: \sf\boxed{\bold{\pink{Area_{(Square)} =\: (Side)^2}}}\: \: \: \bigstar$

Solution :-

Let,

$\mapsto \bf Side_{(Square\: Park)} =\: a\: m$

Given :

• Area of Square Park = 121 m²

According to the question by using the formula we get,

$\implies \sf\bold{\blue{Area_{(Square)} =\: (Side)^2}}$

So,

$\implies \bf Area_{(Square\: Park)} =\: (Side)^2$

$\implies \sf 121 =\: (a)^2$

$\implies \sf \sqrt{121} =\: a$

$\implies \sf \sqrt{\underline{11 \times 11}} =\: a$

$\implies \sf 11 =\: a$

$\implies \sf\bold{\green{a =\: 11}}$

Hence, the required side of a square park is :

$\dashrightarrow \sf Side_{(Square\: Park)} =\: a\: m$

$\dashrightarrow \sf\bold{\red{Side_{(Square\: Park)} =\: 11\: m}}$

$\small \sf\bold{\purple{\underline{\therefore\: The\: side\: of\: a\: square\: park\: is\: 11\: m\: .}}}$

Answer 2

Given :-

⠀

• The area of a square park is 121 m²

⠀

To Find :-

⠀

• Its sides

⠀

Formula Used :-

⠀

$\qquad \bull \: \blue{ \underline{ \boxed{ \sf Area_{Square} = side \times side }}} \: \star$

⠀

Solution :-

⠀

Let the side be x, therefore,

⠀

$\\ \sf \dashrightarrow \: {x}^{2} = 121 \: {m}^{2} \: \: \\ \\ \\ \sf \dashrightarrow \: x = \sqrt{121 \: {m}^{2} } \\ \\ \\ \sf \dashrightarrow \: x = 11 \: m \: \: \: \: \: \: \: \:$

⠀

Therefore, the measure of each side is 11 m.
