Question

find the perimeter.
26 cm
34 cm
40 cm
p = ? cm

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 \( 26 \, \text{cm} \), \( 34 \, \text{cm} \), and \( 40 \, \text{cm} \).

Step3: Calculate the perimeter

Substitute the values into the formula: \( P = 26 + 34 + 40 \). First, \( 26 + 34 = 60 \). Then, \( 60 + 40 = 100 \).

Answer:

\( 100 \)
