Answer 2

$\mathfrak{\large{\underline{\underline{Answer :-}}}}$

The area of the Square is 9.61 cm² and Perimeter of the Square is 12.4 cm

$\mathfrak{\large{\underline{\underline{Explanation :-}}}}$

Given :

Side of the Square = 3.1 cm

To Find :

Area and Perimeter of the Square

Solution :

★ Area of Square = $\boxed{\sf{Side \times Side}}$

$\sf{\longrightarrow} \: 3.1 \times 3.1$

$\sf{\longrightarrow} \:9.61$

Area of the Square is 9.61 cm².

$\rule{300}{1.5}$

★ Perimeter of Square = $\boxed{\sf{Side \times 4}}$

$\sf{\longrightarrow} \:3.1 \times 4$

$\sf{\longrightarrow} \:12.4$

Perimeter of the Square is 12.4 cm

$\therefore$ The area of the Square is 9.61 cm² and Perimeter of the Square is 12.4 cm.

$\rule{300}{1.5}$
