At the Pentagon there are921 feet along each outer side facade and 17.5 miles of corridorS inside it. All sides of the Pentagon are equal. What is the perimeter of the Pentagon

The pentagon has 5 rings, or corridors. You would need to know the spacing between the corridors to figure how much of the 17.5 miles relates to the outermost corridor, and then assume that the perimeter of the pentagon is the same as the length of the outermost corridor.
And that doesn't even count the corridors connecting the rings at various places.
This problem is poorly worded, since there is so much unstated. 
Thank you. I thought so too
