Question :)

• find the perimeter,area and diagonal of a square is 16 cm

Solution :)

(1) Perimeter :-

Perimeter of square = 4 × l

$= 4 \times l \\ = 4 \times 16 \\ = 64 \: cm$

(2) Area :-

Area of square = ${l}^{2}$

$= {l}^{2} \\ = 16 \times 16 \\ = 256 {cm}^{2}$

(3) Diagonal :-

• We know that square have all angles 90° and each diagonal is hypotenuse.

${(16)}^{2} + {(16)}^{2} = {(diagonal)}^{2} \\ \\ 256 + 256 = {(diagonal)}^{2} \\ \\ diagonal = \sqrt{512} \\ \\ diagonal = \sqrt{256 \times 2} = 16 \sqrt{2} \: cm= 22.624 cm$

$\color{Red}{Answer~is~64cm~,~{256cm}^{2}~and~22.624 cm$
