Answer 1

ans. is 10root 2

please tell me it's wrong ya right

Answer 2

Answer:10√2cm

Step-by-step explanation:

Let the perimeter of square =40cm

We know that perimeter of square = 4×side

But perimeter is 40 cm ( given)

40=4× length of side

Length of Side=40/4

=10cm

Consider a square AND

Where AB=BC=CD=DA = 10 cm

Draw a diagonal AC

In ∆AB

AB^2+BC^2=AC^2

10^2+10^2=AC^2

100+100=AC^2

AC^2=200

AC=√200

AC=10√2cm

Thus length of the diagonal = 10√2cm .
