Question

1. The perimeter of a square is 24 cm. Its diagonal is:​

Answer 1

Side of square = (24/2)cm = 12 cm

$diagonal = \sqrt{2} \: side \\ = (\sqrt{2} \times 12)cm \\ = 12 \sqrt{2} \: \: cm$

Answer 2

Answer:

8.48 cm

Step-by-step explanation:

perimeter of square =4 × side

24= 4 × side

24/4 = side

each side of square = 6cm

diagonal of square = √2 × side of square

diagonal = 1.41 × 6
