# One side of the triangle is 25 centimeters 4 centimeters more than the second side and 5

**One side of the triangle is 25 centimeters 4 centimeters more than the second side and 5 cm less than the third, calculate the perimeter of this triangle.**

Find the value of the second side of the triangle, for this you need to reduce the value of the first side of the triangle by 4 cm:

25 cm – 4 cm = 21 cm – the value of the second side of this triangle;

Find the value of the third side of the triangle, for this you need to increase the value of the first side of the triangle by 5 cm:

25 cm + 5 cm = 30 cm – the value of the third side of this triangle;

Let’s find the value of the perimeter of this triangle, for this it is necessary to add the values of all sides of the triangle:

25 cm + 21 cm + 30 cm = 76 cm – the value of the perimeter of the triangle.

Answer: 76 cm is the value of the perimeter of the triangle.
