Answer:

Step-by-step explanation:
It is given that square has the hypotenuse of a right triangle as one of its sides.
Thus, in order to find the hypotenuse of the square, we use the Pythagoras theorem, that is

⇒
⇒
⇒
⇒
Therefore, the length of the hypotenuse will be
.
Now, since square has all the sides of equal measure, therefore the measure of the sides of the square will be
units.
Now, Area of square is given as:



Thus, the area of square is
.
