Calculate the length of the broken line ABC if AB = 13 m 1 dm 2 cm, and BC is 2 times longer than AB.

We calculate the length of the segment BC, if it is given that it is twice as long as AB:
AB = 13 m 1 dm 2 cm; BC = 13 * 2 m 1 * 2 dm 2 * 2 cm = 26 m 2 dm 4 cm;
Let’s calculate the total length of the broken line ABC:
ABC = AB + AC = 13 m 1 dm 2 cm + 26 m 2 dm 4 cm = 13 + 26 m 1 + 2 dm 2 + 4 cm = 39 m 3 dm 6 cm.
Answer: The length of the broken line ABC is 39 m 3 dm 6 cm.
