One side of the triangle is 26 cm, the second is 8 cm larger than the first and the third side is 5 cm

One side of the triangle is 26 cm, the second is 8 cm larger than the first and the third side is 5 cm smaller than the second, Find the perimeter of the triangle

First, we find out what the second side of the triangle is equal to, if, according to the condition of the problem, it is known that it is 8 cm larger than the first:

26 + 8 = 34 centimeters.

Now let’s determine how many centimeters the third side of the triangle is, if, according to the condition of the task, it is known that it is 5 cm less than the second side:

34 – 5 = 29 cm.

It remains to determine what the perimeter of the triangle is if all the lengths of the three sides of the triangle are known:

P = 34 + 26 + 29 = 89 centimeters.

Answer: The perimeter of the triangle is 89 centimeters.
