1. Apply the Pythagorean theorem: c = \sqrt{a^2 + b^2} .
2. Substitute \( a = 19.1 \) and \( b = 16.2 \):
c = \sqrt{{19.1}^2 + {16.2}^2} .
3. Calculate the squares:
{19.1}^2 = 364.81 ,
{16.2}^2 = 262.44 .
4. Add the squares:
364.81 + 262.44 = 627.25 .
5. Take the square root:
\sqrt{627.25}\approx25.044 .
The length of the hypotenuse is approximately 25.044 .
