Answer:
9 square units
Explanation:
1. Count the whole squares inside the figure (yellow): 5
2. Count the half squares inside the figure (where the diagonal line goes from corner to corner in that square; outlined in green) and divide by 2: 6/2=3
3. Because of how the remaining two partial squares are "cut", together they will make 1 whole square: 1
4. Add the totals from steps 1-3: 5+3+1=9
