The perimeter of the triangle is 97 cm, one of the sides is 32 cm, the second is 26 cm. We calculated the length of the third side.

First you need to determine the sum of the lengths of the first and second sides.

Add another 26 cm to the length of the first side.

We get:

32 + 26 = 58 cm.

Since the perimeter of a triangle is the sum of all its sides, in order to find the length of the third side, it is necessary to subtract the sum of the first and second sides from the perimeter of the triangle.

Will be:

97 – 58 = 39 cm.

Answer: The length of the third side of the triangle is 39 cm.
