3 + 7 = 10.

Let us determine how many centimeters the length of one such part will equal, when from the condition of the task we know that the length of the segment AB is equal to fifty-six centimeters:

56: 10 = 5.6.

Let’s determine how many centimeters the length of the BC segment will be equal to:

7 * 5.6 = 39.2.
