Question

Find the Perimeter a square of side 13.1cm . Also find the area of the square

Answer 1

$\textbf{\underline{Answer :-}}$

The Perimeter of the square is 52.4 cm

The area of the square is 171.61 sq.cm

$\textbf{\underline{Explanation :-}}$

$\textsf{\underline{Given :-}}$

Side of the square = 13.1cm

$\textsf{\underline{To find :-}}$

The Perimeter and Area of the Square.

$\textsf{\underline{Solution :- }}$

$\textbf{Perimeter of the square =}$

$\tt {\rightarrow \: side \times 4}$

$\tt{\implies13.1 \times 4}$

$\tt{\implies52.4}$

$\tt{\implies52.4 \: cm}$

Therefore the Perimeter is 52.4 cm

$\textbf{Area :}$

$\tt {\rightarrow \: side \times side}$

$\tt{\implies13.1 \times 13.1}$

$\tt{\implies171.61}$

$\tt{\implies171.61 \: sq.cm}$

Therefore the area of the square is 171.61 sq.cm

$\therefore$The Perimeter of the square is 52.4 cm

$\therefore$The area of the square is 171.61 sq.cm

Answer 2

perimeter of squre =4×side

= 4 × 13.1

= 52.4

area of square = side ×side

=13.1 ×13.1

= 171.61 cm *2
