One side of the triangle is 12 cm, it is 4 cm more than the second side and 3 cm more than the third.

One side of the triangle is 12 cm, it is 4 cm more than the second side and 3 cm more than the third. Calculate the perimeter of this triangle.

A triangle is a geometric figure consisting of three points that do not lie on one straight line and three segments connecting these points. The perimeter of a triangle is equal to the sum of its three sides.
one). Let’s calculate what is the second side of the triangle.
12 – 4 = 8 centimeters.
2) Determine what is the length of the third side of the triangle.
12 – 3 = 9 centimeters.
Let’s answer the question of the problem.
3). Find out what the perimeter of the triangle is.
12 + 8 + 9 = 29 centimeters.
Answer: The perimeter of a triangle is twenty-nine centimeters.
