Ответ:
but
a^2 = d^2 / 2 = x^2 / 2
so area = x^2/2
answer is A. x^2 / 2 or 1/2 (x)^2
Ответ:
d^2=s^2+s^2
d^2=2s^2 we are told that d=x so
x^2=2s^2
s^2=(x^2)/2
And since the area of a square is s^2, the area of this square is:
(x^2)/2
Or as it is shown in your answer choices...
(1/2)x^2 square units (the top answer :P)
