Question

Find the diagonal of a square whose side is 12cm.​

Answer 1

Answer:

Explanation:

side=root 6, perimeter 4root 6

Step-by-step explanation:

Imagine a square of 12 cm length.

square has right angle at every corner.

now draw a diagonal. this forms a isosceles right angle triangle.

find hypotenuse length using pythgorean theorem.

(144 + 144)^1/2 = 12 * 2^1/2

the hypotenuse formed is our diagonal.

answer is 12 root 2

Answer 2

Answer:

$12 \sqrt{2}$

Explanation:

Given side of square is 12cm

diognal of square =

$\sqrt{2 \: \times side}$

$= \sqrt{2 \times 12}$

$= 12 \sqrt{2}$

$= \: diognal \: of \: square \: is \: 12\sqrt{2}$
