Answer:

x = 4√2

Step-by-step explanation:

if its a square, all sides similar of 4 units.

then the bottom and side length is 4 units

we need to find x, the diagonal.

formula: a²+b² =c²

            : 4² + 4² = c²

            : c = √16+16

            : c = √32

            : 4√2

Therefore x, the diagonal is 4√2
