Let s be the side of the square, D the diagonal.

.
Using the Pythagorean theorem,
s%5E2%2Bs%5E2=D%5E2
2s%5E2=D%5E2
D%5E2=100
D=10m

a=s^2
50=s^2
s=sqrt50
s=7.071 ms. is the length of the sides of the square.
Thus the diagonal is c.
a^2+a^2=c^2
50+50=c^2
100=c^2
c=sqrt100
c=10 ms.is the ans. for the length of the diagonal.
