Question

10 which of the following is the perimeter of a triangle with side lengths of 8 in, 9 in, and 11 in? 28 inches 17 inches 25 inches 16 inches

Explanation:

Step1: Recall perimeter formula

The perimeter \( P \) of a triangle is the sum of its three side lengths. So, \( P = a + b + c \), where \( a \), \( b \), and \( c \) are the side lengths.

Step2: Substitute the values

Given \( a = 8 \) in, \( b = 9 \) in, and \( c = 11 \) in. Then \( P = 8 + 9 + 11 \).

Step3: Calculate the sum

\( 8 + 9 = 17 \), and \( 17 + 11 = 28 \).

Answer:

28 inches
