I think @Howie_Hua sums up what I think about these types of questions. Don't get me wrong, I think they are great. But they also show students that algebra doesn't have to be as hard as it seams.

Mathematics.

Don't you just love Golygons? A "Golygon" is any polygon with all right angles (a rectilinear polygon) whose sides are consecutive integer lengths.

The smallest Golygon (below) has 8 sides. It's the only solution with fewer than 16 sides. https://t.co/LBKXsGKEsM pic.twitter.com/wjKoL5ENzI
