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.
