Question

find the perimeter.
25 ft
25 ft
17 ft
p = ? ft

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: Substitute the values of the side - lengths

Here, \(a = 25\) ft, \(b = 25\) ft, and \(c = 17\) ft. Then \(P=25+25 + 17\).

Step3: Calculate the sum

\(25+25+17=(25 + 25)+17=50+17 = 67\).

Answer:

\(67\)
