Find the perimeter of triangle MNP if the length of the MN side is 24 cm, which is 2 cm less than the length of the NP side, and the length of the MP side is 4 cm longer than the NP side.

In order to find the perimeter of a triangle, you need to find the lengths of all sides of the triangle.

By the condition of the problem, the length of the MN side is 24 cm, which is 2 cm less than the length of the NP side. Find the length of the NP side by adding 2 cm to the length of the MN side:

1) 24 + 2 = 26 (cm).

It is also known that the length of the MP side is 4 cm longer than the NP side. Find the side length MP by adding 4 cm to the side length NP:

2) 26 + 4 = 30 (cm).

Find the perimeter of the triangle MNP by adding the lengths of the sides of the triangle NP, MP and MN:

3) P = 24 + 26 + 30 = 80 (cm).

Answer: The perimeter of the MNP triangle is 80 cm.
