The length of the first link of the broken line is 1 dm, the length of the second one is 3 cm less. Draw this broken line. Find out its length.
Let’s find the length of the second link of the polyline. If it is 3 cm less, then you need to subtract 3 cm. 1 dm = 10 cm.
10 – 3 = 7 (cm).
Let’s draw a broken line, the first link is 10 cm long, the second link is 7 cm.
The length of the polyline is equal to the sum of the lengths of its links.
10 + 7 = 17 cm
Answer. 17 cm.
