Using Pythagoras:
side_length² + side_length² = diagonal²
→ 2 × side_length² = (3√2)²
→ 2 × side_length² = 3³ × 2
→ side_length² = 3²
→ side_length = 3
→ perimeter = 4 × side_length = 4 × 3 = 12 units.

Diagonal of a square whose area is 36?
The diagonal of a square whose area is 36 is the square root of 72, or about 8.49. Since the area of a square is side(squared), then the sides are each 6. Then since a(squared) + b(squared) = c(squared), for a triangle (the diagonal), you get the square root of 72.
