5.477
Step-by-step explanation:
Here we have to get the value √ (x²+y²) in this question where the values of x² and y² are given to be 20 and 10 respectively.
Let A = √ (x²+y²) = √ (20+10) {Since the value of x² = 20 and that of y² = 10}
⇒ A = √30 = 5.477
Therefore, the value of √ (x²+y²) is 5.477. (Answer)
