8. To find the answer you can eather multipy it for each of the sides or you can add it 6 times once for each side
9. You basicly do the same thing as the previous problem but with the new numbers and you add each number 2 times
10. For Area are you multiply Base × Height So all you have to do is Multiply the 2 numbers together
11-12 Is the same but witb the new numbers
I hope this helps!
