Consider the following program. It is supposed to compute the hypotenuse of a right triangle after the user enters the lengths of the other two sides.
a = float(input("Enter the length of the first side:"))
b = float(input("Enter the length of the second side:"))
h = sqrt(a * a + b * b)
print("The length of the hypotenuse is", h)
When this program is run, the following output is generated (note that input entered by the user is shown in bold):
Enter the length of the first side: 3
Enter the length of the second side: 4
Traceback (most recent call last):
h = sqrt(a * a + b * b)
NameError: name 'sqrt' is not defined
Why is this error occurring? How would you resolve it ?

The error is coming because math module is not imported in the code. To resolve it, we should import the math module using the import statement import math.

Find out the error and the reason for the error in the following code. Also, give the corrected code.
a, b = "5.0", "10.0" x = float(a/b) print(x)
