Answer:

Diagonal is 35 cm.

Step-by-step explanation:

We can solve it by using Pythagoras Theorem.

In this case Hypotenuse = Diagonal

We know that,

Side² + Side² = Hypotenuse²

28² + 21² = Hypotenuse²

784 + 441 = Hypotenuse²

1225 = Hypotenuse²

√1225 = Hypotenuse

35 = Hypotenuse

Therefore, the length of its diagonal is 35 cm.
