The diagonal of a square is the hypotenuse of an isosceles right triangle with two adjacent sides of the square forming the legs of the triangle. Let 
represent the measure of the given diagonal. Let 
represent the measure of the side of the square. Mr. Pythagoras said, if you recall, that the square of the hypotenuse, 
in this case, is equal to the sum of the squares of the other two sides, that is 
in this case, so:
Multiply by 
But 
is the area of the square, so to find the area of a square given the measure of a diagonal, square the diagonal and divide the result by 2.
