In a triangle, one side is 8 cm, the second is 125% of the first, and the third is 60% of the second.

In a triangle, one side is 8 cm, the second is 125% of the first, and the third is 60% of the second. Find the perimeter of the triangle.

1) Divide 8 cm by 100% and multiply the result by 125%, thereby calculating the length of the second side:

8: 100 * 125 = 0.08 * 125 = 10 cm.

2) Now let’s calculate the length of the third side, for this we divide the length of the second side by 100% and multiply the result by 60%:

10: 100 * 60 = 0.1 * 60 = 6 cm.

3) Knowing the lengths of all three sides, we find the perimeter of a given triangle as the sum of the lengths of the sides:

8 + 10 + 6 = 24 cm.

Answer: the perimeter of the triangle is 24 cm.
