A=s^2
50=s^2
let c=diagonal a and b the sides
a=s
b=s
a^2+b^2+c^2 where c=the diagonal and both a^2 and b^2 =s^2
The diagonal will be 2s^2=c^2
2*50=c^2
100=c^2
c=10 the diagonal equals 10

Pythagoras says that the measure of the diagonal of a square is the square root of 2 times the measure of one of the sides squared.



But since the measure of a side squared is the area of a square we can write:



Substitute the given area for A and do the arithmetic.
