Explanation:

Step1: Recall perimeter formula for triangle

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

Step2: Identify the side lengths

From the triangle, the side lengths are \( 17\) km, \( 17\) km, and \( 19\) km.

Step3: Calculate the perimeter

Substitute the values into the formula: \( P = 17 + 17 + 19 \). First, \( 17 + 17 = 34 \). Then, \( 34 + 19 = 53 \).

Answer:

53
