Question

find the perimeter.
25 m
18 m
36 m
p = ? m

Explanation:

Step1: Recall the formula for perimeter

Perimeter of a triangle \(P=a + b+ c\)

Step2: Substitute the side lengths

\(a = 25\), \(b = 18\), \(c = 36\). So \(P=25 + 18+36\)

Step3: Calculate the sum

\(25+18 = 43\), then \(43+36=79\)

Answer:

79
