One side of the triangle is 17 cm, the other side is 8 cm larger than the first

One side of the triangle is 17 cm, the other side is 8 cm larger than the first, and the third side is 6 cm smaller than the second. What is the perimeter of this triangle?

Brief record of the task:

1st side – 17 cm;

2nd side -? cm, 8 cm more than 1st;

3rd side -? cm, 6 cm less than the 2nd;

perimeter of the triangle -? cm.

1. Calculate the length of the 2nd side of the triangle:

17 + 8 = 25 cm.

2.3rd parties:

25 – 6 = 19 cm.

3. Calculate the perimeter of the figure:

17 + 25 + 19 = 61 cm.

Answer: The perimeter of the triangle is 61 centimeters.
