Answer:

13 cm

Explanation:

The diagonal of a rectangle forms a right triangle; where the diagonal is a hypotenuse, and two sides of the rectangle are legs.

Using pythagorean's theorem (
a^2 + b^2 = c^2 ), we can say:

$5^2 + 12^2 = c^2\\25 + 144 = c^2\\169 = c^2\\13 = c$

The hypotenuse is equal to 13cm.
