The length of the first segment is 25 cm, the length of the second segment is 17 cm longer than the length of the first and the length of the third is 12 cm less than the sum of the lengths of 1 and 2 segments, find the length of the length of 3 segments.
If the length of the second segment is 17 cm longer than the first, then:
25 + 17 = 42 cm – the length of the second segment;
Let’s find the sum of the lengths of the first and second segment:
25 + 42 = 67 cm;
The length of the third segment is less than the sum of the first and second by 12 cm, then:
67 – 12 = 55 cm – the length of the third segment;
Answer: the length of the third segment is 55 cm.
