1. From the data presented in the problem statement, we know that the perimeter of the triangle is 16 cm.
2. Since we know that the length of one of the sides is 5 cm, let us assume that this is the base and find the sum of the lengths of the other two sides.
16 – 5 = 11 cm.
3. Let’s calculate what is the length of one side if the triangle is equilateral.
11/2 = 5.5 cm.
4. If we assume that 5 cm, this is the length of one of the sides, which are equal to 5 cm, therefore the second side is 5 cm. Then we calculate what the base will be equal to.
16 – 5 * 2 = 16 – 10 = 6 cm.
