Answer:

1.41a

Step-by-step explanation:

Let ABC is a right triangle with equal legs AB =BC.  

Hence, ∠B is 90° and CA is the hypotenuse.

Now, applying Pythagoras Theorem, we can write  

CA² = AB² + BC²

Let us assume that each legs AB = BC = a.

Therefore, CA² = a² +a² = 2a²

Hypotenuse or CA = a√2 = 1.41a { Round to the nearest tenth} (Answer)
