Answer: 13.6

Explanation:

To find the length of the third side of a triangle when the perimeter is given, subtract the sum of the lengths of the known sides from the total perimeter.

Given:

Perimeter = 36.9 inches

Side 1 = 9.7 inches

Side 2 = 13.6 inches

Let's calculate the length of the third side:

Perimeter = Side 1 + Side 2 + Side 3

36.9 = 9.7 + 13.6 + Side 3

We can rearrange the equation to solve for Side 3:

Side 3 = Perimeter - (Side 1 + Side 2)

Side 3 = 36.9 - (9.7 + 13.6)

Side 3 = 36.9 - 23.3

Side 3 = 13.6

Therefore, the length of the third side is 13.6 inches.
