Answer 2

For this case we have to:

Let "a" be the side of the square. Then, the area "A", will be given by:

`A = a * a = a ^ 2`

Also, by the Pythagorean theorem we have to:

`x ^ 2 = a ^ 2 + a ^ 2\\x ^ 2 = 2a ^ 2\\\frac {x ^ 2} {2} = a ^ 2`

Finally the area is:

`A = \frac {x ^ 2} {2}`

Answer:

Option A
