Question

find the perimeter. 15 in 9 in 12 in p = ? in

Explanation:

Step1: Recall the formula for perimeter of a triangle

Perimeter \( P=a + b + c\), where \(a\), \(b\), \(c\) are the side lengths of the triangle.

Step2: Identify the side lengths

Here, \(a = 15\) in, \(b=9\) in, \(c = 12\) in.

Step3: Calculate the perimeter

\(P=15+9 + 12\)
\(P=36\)

Answer:

\(36\)
