Question

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

Explanation:

Step1: Recall the formula for perimeter of a triangle

The perimeter \( P \) of a triangle with side lengths \( a\), \( b\), and \( c \) is \( P=a + b+ c\).

Step2: Substitute the given side lengths

Here, \( a = 26\space\text{cm}\), \( b = 34\space\text{cm}\), and \( c = 40\space\text{cm}\). So \( P=26 + 34+40\).

Step3: Perform the addition

First, \( 26+34 = 60\). Then \( 60 + 40=100\).

Answer:

\(100\)
