One side of the triangle is 6 cm. The second side is two thirds of the length of the first side, and the third side is 0.75 of the first side. Find the perimeter of the triangle.

1. First, we need to know the length of the second side. To do this, divide the length of the first side by 3, and then multiply by 2. We get:

6: 3 * 2 = 4 (cm) – the length of the second side.

2. Now we need to know the length of the third side. To do this, we need to multiply the length of the first side by 0.75. We get:

6 * 0.75 = 4.5 (cm) – the length of the third side.

3. Now we can find out the perimeter of the triangle. To do this, use the formula P = a + b + c. Substitute the given values into the formula and calculate. We get:

6 + 4 + 4.5 = 14.5 (cm) – the perimeter of the triangle.

Answer: 14.5 cm.
