Video Summary

Mary drew six identical squares with shaded regions inside. The task was to determine how many shaded regions have a perimeter equal to the square's perimeter. By tracing the perimeters, it's observed that if a line drawn through the square intersects the shaded region's boundaries more than twice, the perimeters don't match. Upon examination, two of the six squares have this issue, leaving four squares where the shaded region's perimeter matches the square. Therefore, the answer to the problem is four.
