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)
