Question

Find the length of the diagonal of a square of side 12cm. 0

Answer 1

Diagonal of square =
$\sqrt{2} a$
a = 12

Root 2 = 1.4

Diagonal = 1.4 x 12
= 16.97 cm

Answer 2

The length of the diagonal of a square is 16.968 cm $(12\sqrt{2} cm)$.

Step-by-step explanation:

Given by question, the side of square (a) = 12 cm

Find the diagonal of a square = ?

We know that,

The length of the diagonal of a square = $\sqrt{2}$ ·Side(a)

∴ The length of the diagonal of a square = $\sqrt{2}$ ·12 cm

$= 12\sqrt{2} cm$

$= 12\times 1.414$

[ ∵ $\sqrt{2} =1.414$]

$=16.968cm$

Hence, the length of the diagonal of a square is 16.968 cm $(12\sqrt{2} cm)$.
