Video Summary

The problem involves determining the length of a side covered by identical rectangular tiles, where each tile has a shorter side of one meter. By examining the arrangement, it's established that the longer side of each rectangle is 4 meters, aligned with four 1-meter shorter sides. Calculating the total length across involves adding: 1 meter + 4 meters + 1 meter + 1 meter + 4 meters + 1 meter, resulting in a total length of 12 meters. Thus, the length of the side with the question mark is 12 meters, making the correct answer E, 12 meters.
