To find the length of the hypotenuse in a right triangle with legs of lengths 12 cm, you can use the Pythagorean theorem, which states:
\[ c = \sqrt{a^2 + b^2} \]
where \( c \) is the length of the hypotenuse, and \( a \) and \( b \) are the lengths of the legs. In this case, both legs \( a \) and \( b \) are 12 cm.
So, substituting the values into the formula:
\[ c = \sqrt{12^2 + 12^2} = \sqrt{144 + 144} = \sqrt{288} \]
Now, calculate \( \sqrt{288} \):
\[ \sqrt{288} \approx 16.97 \]
So, rounding to the nearest hundredth, the length of the hypotenuse is approximately 16.97 cm.
Therefore, the correct response is:
16.97
