To find the length of the hypotenuse (c) in a right triangle, you can use the Pythagorean theorem, which states:

\[ c = \sqrt{a^2 + b^2} \]

where \(a\) and \(b\) are the lengths of the two legs of the triangle.

In your case, you provided:

  • \(a = 3 , \text{cm}\)
  • \(b = 2 , \text{cm}\)

Now, we can calculate the hypotenuse:

\[ c = \sqrt{(3 , \text{cm})^2 + (2 , \text{cm})^2} \]

Calculating the squares:

\[ c = \sqrt{9 , \text{cm}^2 + 4 , \text{cm}^2} \] \[ c = \sqrt{13 , \text{cm}^2} \] \[ c \approx 3.60555 , \text{cm} \]

Rounding to the nearest tenth, the length of the hypotenuse is:

\[ c \approx 3.6 , \text{cm} \]
