Answer:
28 square units
Explanation:
The area of the shaded region is the difference of the area of the large square and the combined area of the two small squares.
large square: 6 units by 6 units
area = 6² = 36
small square: 2 units by 2 units
area = 2² = 4
area of shaded region = 36 - 4 - 4 = 28
Another method is to count the number of little shaded squares.
