а) $$|SD| = |7.45 - 1.15| = |6.3| = 6.3$$
б) $$|RT| = |-5.3 - (-8.93)| = |-5.3 + 8.93| = |3.63| = 3.63$$
в) $$|KL| = |9.43 - (-9.43)| = |9.43 + 9.43| = |18.86| = 18.86$$
г) $$|AB| = |-5\frac{1}{3} - 3\frac{2}{3}| = |-5\frac{1}{3} + (-3\frac{2}{3})| = |-8 - \frac{1+2}{3}| = |-8 - \frac{3}{3}| = |-8 - 1| = |-9| = 9$$
