Need help been waiting for 2 hours to find a answer

1. 30 units squared and 22 units

2. 28 units squared and 28 units

3. 9 units squared and 12 units

4. 21 units squared and 20 units

Step-by-step explanation:

You just multiply by each parrallel for one 6 units high and 5 units wide, do this for 1, 3, and 4, but for 2 you have to break it into 2 shapes. Draw an extra line from (1,0) to (1, -2) then multiply each shape separately, then erase the line and count each block along the lines.
