The 6.3 cm side of the triangle is 20.8 cm shorter than the second side and 0.9 cm longer

The 6.3 cm side of the triangle is 20.8 cm shorter than the second side and 0.9 cm longer than the third side Find the triangle’s perimeter.

1. The perimeter of a triangle is equal to the sum of the lengths of all its sides. You must first determine the length of each.

2. Find the second side of the triangle. Since the first side, equal to 6.3 cm, is less than the second by 20.8 cm, you need to add these numbers. 20.8 + 6.3 = 27.1.

3. Find the third side. The first side is 0.9 cm larger than the third. 6.3 – 0.9 = 5.4.

4. Now add the resulting numbers (the lengths of the sides of the triangle). 6.3 + 27.1 + 5.4 = 38.8.

5. Answer: 38.8 centimeters.
