1. The question "What about length?" is a bit broad, so let's clarify what kind of length you're asking about. 2. If this relates to a math problem or geometric figure, length usually refers to the measure of a line segment or the distance between two points. 3. To find the length of a segment between two points $(x_1, y_1)$ and $(x_2, y_2)$, we use the distance formula: $$\text{Length} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$ 4. This formula comes from the Pythagorean theorem, finding the hypotenuse of a right triangle formed by the horizontal and vertical distances. 5. If you provide more details or a specific problem, I can help calculate or explain length accordingly.
