Answer:

x = 12√2

Step-by-step explanation:

if its a square, all sides similar of 12 units.

then the bottom and side length is 12 units

we need to find x, the diagonal.

formula: a²+b² =c²

            : 12² + 12² = c²

            : c = √144+144

            : c = √288

            : c = 12√2

Therefore diagonal, x is 12√2
