Explanation:

Step1: Recall perimeter formula

Perimeter of a polygon is the sum of all its side lengths.

Step2: Identify side lengths

The sides are 26 km, 29 km, 33 km, and 29 km.

Step3: Sum the side lengths

Perimeter \( = 26 + 29 + 33 + 29 \)
\( = 26 + (29 + 33) + 29 \)
\( = 26 + 62 + 29 \)
\( = 88 + 29 \)
\( = 117 \)

Answer:

117
