How Big is Texas

How big is Texas?

Their route, which started in the North Texas town of Gainesville, would take them 3,331 miles around the state. (For reference, the drive from New York City to Los Angeles is about 2,800 miles.) They kept to major roads while sticking as close as possible to the state’s borders, which was particularly difficult in wide-open West Texas.

How big is Texas?

I don't think you can work it out from the distance they travelled. They were sticking to major roads, so the 'coastline' would be measured very inaccurately I should imagine.

The smaller the steps, the closer you can get to the edge, so the longer the coastline gets. Though Texas does have rather a lot of Murican-style straight-line boundaries, just not as many as that rather over-simplified stone map would suggest...
