Question

find the perimeter.
15 in
10 in
15 in
p = ? in

Explanation:

Step1: Recall the formula for perimeter of a triangle

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

Step2: Identify the side - lengths

Here, \(a = 15\) in, \(b = 10\) in, \(c = 15\) in.

Step3: Calculate the perimeter

Substitute the values into the formula: \(P=15 + 10+15\).
