$\sf\underbrace{Appropriate\: Question:}$

• Area o circle is equal to area of square radius of circle is 7 cm find perimeter of square..?

$\bf\underline{Given:}$

• Area of circle and area of square are equal.
• Radius of circle is 7 cm.

$\bf\underline{To\:Find:}$

• Perimeter of square.

$\bf\underline{Solution:}$

$\sf\underline{Area \:of \:circle\: =\: πr²}$

• $\implies$ Area = 22/7 × (7)²

• $\implies$ Area = 22/7 × 49

• $\implies$Area = 1078/7

• $\implies$ Area = 154

Area of circle is 154 cm².

Area of circle and area of square are equal.

So,

• Area of square is 154 cm².
• We will find side of square using it's area.

Area of square = Side × Side [Or, Side²]

• $\implies$ 154 = Side²

• $\implies$ √154 = Side

• $\implies$Side = 12.40

Side of square is 12.40 cm (approx).

We know,

Perimeter of square = 4 × side

• $\implies$Perimeter = 4 × 12.40
• $\implies$Perimeter = 49.6

Therefore,

Perimeter of square is 49.6 cm (approx).
