The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (C) is equal to the sum of the squares of the other two sides. It can be written as:
C² = A² + B²
Here, you've given the two sides as 12 meters and 9 meters. These are the legs (A and B) of the right triangle. To find the hypotenuse (C), follow these steps:
- Square both side lengths:
12² = 144
9² = 81 - Add these squares:
144 + 81 = 225 - Take the square root of the sum to find C:
C = √225 = 15
Answer: The length of side C is 15 meters.
