Answer:
You must be in 8th grade?
Step-by-step explanation:
For the first one I don't know.
The second one I'm also not sure about.
The third one, the answer is 225 because you will divided 150 by 2 and get the answer of 75 and then multiply 75 by 3 to get the answer of 225.
For the fourth one, you will multiply 5 x 2.5 = 12.5 then you will multiply 12.5 x 20 = 250yd^2.
For the last one you will multiply 2.25 x 22 = 49.5 miles.
