Question

What is the total number of unique triangles with side lengths of 6.5 centimeters, 6 centimeters, and 2.5 centimeters?\

Answer 1

Answer:

Total 9 unique triangles can be formed

Step-by-step explanation:

For triangles to be unique, length of one side can be arranged in 3 different ways

Let us  L1, L2 and L3 are the three sides

Now, length of 6.5 cm can be at maximum three positions i.e  L1, L2 and L3

Like wise length of 6.0 cm can be at maximum three positions i.e  L1, L2 and L3

and length of 2.5 cm can be at maximum three positions i.e  L1, L2 and L3

Hence, total ways of making unique triangles are

3 + 3+ 3= 9
