In a triangle, one side is 24 cm, and it is 8 cm less than the second side and 4 cm less than the third side. Find the perimeter of this triangle.

It is known that the first side is 8 cm less than the second side, we find the length of the second side:

1) 24 + 8 = 32 (cm) – the length of the second side;

It is known that the first side is 4 cm less than the third side, we find the length of the third side:

2) 24 + 4 = 28 (cm) – the length of the third side.

In order to find the perimeter of a triangle, you need to find the sum of all sides of the triangle. Find the sum of the first side, second side and third side of the triangle:

3) 24 + 32 + 28 = 84 (cm) – the perimeter of the triangle.

Answer: 84 cm.
