find the area of a square with diagonals??
:
Let x = length of the diagonal
Let s = length of the side
then s^2 = area of the square
:
Find the length of the sides using the diagonal, using pythag.
s^2 + s^2 = x^2
:
2s^2 = x^2
:
s^2 = x%5E2%2F2,
:
we can say the area of square with a diagonal of x = x%5E2%2F2
