Answer

The meterstick must be oriented in a direction perpendicular to its own motion.

Work Step by Step

This stick is traveling at relativistic speed, since $\gamma = 2$. This means that it is contracted along its direction of motion by a factor of two. The fact that its length is still one meter means that it is not pointing in the direction of motion. The meterstick appears just as long, but only half as thick.
