Question

find the perimeter. include the unit. 8 in 10 in 11 in

Explanation:

Step1: Recall perimeter formula for triangle

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 lengths of the sides.

Step2: Identify the side lengths

From the triangle, the side lengths are \( 8 \) in, \( 10 \) in, and \( 11 \) in.

Step3: Calculate the perimeter

Substitute the values into the formula: \( P = 8 + 10 + 11 \). First, add \( 8 \) and \( 10 \): \( 8 + 10 = 18 \). Then, add \( 18 \) and \( 11 \): \( 18 + 11 = 29 \).

Answer:

29 inches
