To display Giani's data about the distance traveled to the store and the time spent in the store for 25 people in a matrix format, he would need a **25 x 2 matrix**.
In this matrix:
- Each row (25 rows) represents one individual from the 25 people surveyed.
- The first column represents the distance traveled to the store.
- The second column represents the time spent in the store.
Therefore, the matrix structure would be represented as 25 (for the individuals) x 2 (for the distance and time variables).
