Answer:
second option
Step-by-step explanation:
The perimeter is the sum of the 3 sides of the triangle
Given
hypotenuse = x and
the combined length of the legs = 2x , then
perimeter = x + 2x
The cross product of two vectors gives a third vector 
that is orthogonal to the first two.
Normalize this vector by dividing it by its norm:
To get another vector orthogonal to the first two, you can just change the sign and use
