The length of one side of the triangle is 360 cm, the second is 50 cm less. The third side is 1/3 the length of the first side. Indicate what is the sum of the lengths of the sides of the triangle.

1. From the data presented in the statement of the problem, we know that the length of the first side in a triangle is 360 cm.

2. Determine what is the length of the second side of this triangle if it is 50 cm less than the length of its first side.

360 – 50 = 310 cm.

3. Next, define what is the length of the third side, if its length is 1/3 of the length of the first side.

360 * 1/3 = 360/3 = 120 cm.

4. Now calculate what is the sum of the lengths of all sides of this triangle.

360 + 310 + 120 = 790 cm or 79 in.
