The length of the broken line, consisting of four links, is 13.25 cm. The length of the first link is 6.3 cm

The length of the broken line, consisting of four links, is 13.25 cm. The length of the first link is 6.3 cm, the second is 2 times less than the first, the rest of the links are of equal length. Calculate the lengths of the second and third links of the polyline?

By the first action, we find out the value of the second link, which is 2 times less than the first. 6.3: 2 = 3.15 cm.

Next, you need to find out how long the third and fourth links have together. Subtract the sum of the values of the first and second links from the total length. 13.25 – (6.3 + 3.15) = 3.8 cm.

The third and fourth links are of the same length, so you need to divide 3.8 by 2.38: 2 = 1.9 cm.

Answer: the length of the second link is 3.15 cm, the third link is 1.9 cm.
