Question

the side of the square is 12 cm find(a) perimeter (b)diagonal​

Answer 1

Answer:

(a) 48 cm (b) 12√2

Step-by-step explanation:

(a)

Perimeter of square = 4×side

= 4×12

= 48 cm

(b)

Diagonal of square = side×√2

= 12 × √2

= 12√2 cm.

Answer 2

Answer:

A) perimeter of a square = side×4

12×4

=48 cm

So the perimeter Is 48 cm

B) To Find Diagonal = side × $\sqrt{2}$

= $12 \times \sqrt{2}$

$= 12 \sqrt{2}$

So the measure of diagonal is $12 \sqrt{2}$
