| **The side of the triangle that is 6.3 cm is 20.8 cm less than the second side and 0.9 cm more than the third side, find the perimeter.**

Find the second side of the triangle.

Since the first side is 20.9 cm less than the second, we get:

6.3 + 20.8 = 27.1 cm.

We find the third side.

Since the first is 0.9 cm more than the third, we get:

6.3 – 0.9 = 5.4 cm.

Find the perimeter of the triangle.

To do this, we sum up the values of the sides of the triangle.

We get:

6.3 + 27.1 + 5.4 = 38.8 cm.

Answer:

The perimeter of the triangle is 38.8 cm.
