Answer 5

If you use Pythagorean Theorum the hypotenuse squared is going to equal the squares of the other two sides (which are equal). So,

(3√2)^2 = x^2 + x^2
9(2) = 2x^2
18 = 2x^2
9 = x^2
3 = x, so each side is 3 units long.
A square has four sides, so the perimeter is 3 x 4 or 12 units in length.
