What is the area calculation represented by A² + B² = C²?

The equation A² + B² = C² represents the Pythagorean theorem, which is a fundamental principle in geometry specifically related to right triangles. In this context, A and B represent the lengths of the legs of the triangle, while C represents the length of the hypotenuse, which is the side opposite the right angle. The theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. This allows for the calculation of the hypotenuse when the lengths of the other two sides are known, making option C the correct interpretation of the equation.

Perimeter and volume calculations involve different formulas and do not relate directly to the properties defined in this theorem. Similarly, determining angle measures is not represented by this equation, as it specifically addresses side lengths rather than angular relationships.
