Area = side^2 = 100
Side is 10
Diagonal of square is side * sqrt(2)
In this case its 10 * sqrt(2) (Option B)

In determining the length of diagonal XZ, we may recall that the diagonal of a square is always equal to side√2.

Since the area of the square is 100, and area = side^2, the side of the square is equal to 10.

Thus, the diagonal = 10√2.

Answer: B
