Calculate the length of the broken line, consisting of three segments, if their lengths are equal

Calculate the length of the broken line, consisting of three segments, if their lengths are equal to 6 cm 3 mm, 4 cm 9 mm and 5 cm 8 mm.

To find the length of a polyline, you need to find the sum of all its links.

1) For convenience of calculations, we express the length of the broken line links in mm:

6 cm 3 mm = 63 mm;

4 cm 9 mm = 49 mm;

5 cm 8 mm = 58 mm.

2) Find the length of the polyline:

63 + 49 + 58 = 170 (mm) – the length of the broken line.

3) Let us express the length of the polyline in cm:

170 mm = 17 cm.

Answer: the length of the broken line is 17 cm.
