Answer:
The length of the diagonal line is 26 cm
Step-by-step explanation:
In this question, we are trying to find length of the diagonal line in the rectangle.
To find this, we would use the Pythagorean theorem:
a² + b² + c² = d²
Plug in the variables from the image and solve:
24² + 8² + 6² = d²
Solve for d:
24² + 8² + 6² = d²
576 + 64 + 36 = d²
640 + 36 = d²
676 = d²
To cancel the exponent, we would square root both sides.
√676 = √d^2
26 = d
26 cm would be your answer.
