Answer 1

Answer:

3.5 centimeters.

Step-by-step explanation:

If the perimeter is equal to 11.5 centimeters, and we have the lengths of 2 sides, we can add them together and subtract that sum from the perimeter to get the value of the missing side length.

2.5 + 5.5 = 8

11.5 - 8 = 3.5

Therefore, the side length is equal to 3.5.

Answer 2

Answer:

3.5

Step-by-step explanation:

11.5 - 2.5 = 9

9 - 5.5 = 3.5

and scalene triange means none of the 3 sides are equal...

3.5 does not equal 5.5 or 2.5
