To find the length of the diagonal AB, we can first find the length of the diagonal CB using the Pythagorean Theorem.
CB = √(3^2 + 4^2) = √(9 + 16) = √25 = 5
Then, we can use CB as a leg of the right triangle ACB, with AB being the hypotenuse.
So, AB = √(5^2 + 12^2) = √(25 + 144) = √169 = 13
Therefore, the length of the diagonal AB is approximately 13 cm.
