Question: What is the length of the diagonal of a rectangle with length 8 units and width 6 units?

Options:

1. 10
2. 12
3. 14
4. 16

Correct Answer: 10

Solution:

The length of the diagonal (d) of a rectangle can be calculated using the Pythagorean theorem: d = √(length² + width²). Here, d = √(8² + 6²) = √(64 + 36) = √100 = 10.
