Final answer:
The length of the polygon with side lengths 49 in, 46 in, 72 in, and 118 in is 285 in.
Step-by-step explanation:
To find the length of a polygon, you need to add up the lengths of all its sides. In this case, the polygon has side lengths of 49 in, 46 in, 72 in, and 118 in.
To find the total length, you can add these lengths together: 49 + 46 + 72 + 118 = 285.
Therefore, the length of the polygon is 285 in.
